Logic IC

SN74HC245 · Texas Instruments

The 74HC245 is an octal bus transceiver with 3-state outputs for asynchronous two-way data transfer between two 8-bit buses. A DIR pin sets direction and OE isolates the buses when high.

SN74HC251 · Texas Instruments

The 74HC251 is an 8-to-1 multiplexer with 3-state outputs that can interface directly with a system bus or drive up to 15 LSTTL loads.

SN74HC253 · Texas Instruments

The SN74HC253 is a dual 4-to-1 multiplexer with 3-state outputs, used for data selection and parallel-to-serial conversion.

SN74HC259 · Texas Instruments

The 74HC259 is an 8-bit addressable latch designed for general-purpose storage applications, capable of operating in various modes including latching data, memory retention, and demultiplexing.

SN74HC27 · Texas Instruments

The 74HC27 is a triple 3-input NOR gate IC that performs Boolean function Y = A + B + C, suitable for alarm/tamper detect circuits and S-R latches.

SN74HC273 · Texas Instruments

The 74HC273 contains eight positive-edge-triggered D-type flip-flops with a common clock and a shared active-low direct clear. It is well suited to buffer, storage, and pattern-generator registers.

SN74HC32 · Texas Instruments

The 74HC32 is a high-speed CMOS logic IC with four independent 2-input OR gates, each performing Y = A + B. It runs from 2V to 6V and drives up to 10 LSTTL loads.

SN74HC365 · Texas Instruments

The 74HC365 is a hex buffer with 3-state outputs that can drive up to 15 LSTTL loads and has low power consumption.

SN74HC367 · Texas Instruments

The 74HC367 is a hex buffer that can pass noninverted data from inputs to outputs or place the outputs in high-impedance state based on OE input.

SN74HC373 · Texas Instruments

The 74HC373 is an octal transparent D-type latch with 3-state outputs. While latch-enable (LE) is high the outputs follow the inputs; taking LE low holds the data, and OE controls the bus drivers.

SN74HC374 · Texas Instruments

The 74HC374 is an octal edge-triggered D-type flip-flop with 3-state outputs. On the rising clock edge the eight Q outputs capture the D inputs; an output-enable pin places the outputs in high impedance.

SN74HC377 · Texas Instruments

The 74HC377 is an octal D flip-flop with a positive-edge-triggered enable input, used for data storage and synchronization in digital circuits.

SN74HC393 · Texas Instruments

The 74HC393 is a dual binary counter IC that provides two independent 4-bit counters, each with clock and clear inputs.

SN74HC42 · Texas Instruments

The 74HC42 BCD-to-Decimal Decoder converts binary-coded decimal (BCD) inputs to seven-segment display codes.

SN74HC540 · Texas Instruments

74HC540 is an octal buffer with inverted data outputs, designed for use in digital circuits with a wide operating voltage range.

SN74HC541 · Texas Instruments

74HC541 is an octal buffer that provides high-current 3-state outputs and can be used in various applications like LEDs, servers, PCs, and wearable devices.

SN74HC574 · Texas Instruments

The SN74HC574 is an octal D flip-flop with 3-state outputs, designed for bus driving and suitable for buffer registers, I/O ports, bidirectional drivers, and working registers.

SN74HC688 · Texas Instruments

The 74HC688 is an 8-bit comparator that performs binary or BCD word comparisons and outputs the result based on the inputs P and Q.

SN74HC74 · Texas Instruments

The 74HC74 holds two independent positive-edge-triggered D-type flip-flops, each with asynchronous active-low preset and clear and complementary Q/Q outputs. It runs from 2V to 6V.

SN74HC86 · Texas Instruments

The 74HC86 is a high-speed CMOS logic IC with four independent 2-input exclusive-OR (XOR) gates. It operates from 2V to 6V and is used for phase detection and selectable inverter/buffer functions.

SN74LVC1G08 · Texas Instruments

A single 2-input positive-AND gate IC that supports 5V operation and has low power consumption.

SN74LVC1G125 · Texas Instruments

The SN74LVC1G125 is a single line driver buffer gate with a 3-state output designed for VCC operation between 1.65V and 5.5V.
