SN74AHCT157PWR by Texas Instruments

The SN74AHCT157PWR is a high-performance, quadruple 2-line to 1-line data selector/multiplexer from Texas Instruments, designed to operate on a 4.5V to 5.5V VCC range. This integrated circuit is part of the 'AHCT' family, which signifies that it combines CMOS technology with TTL-compatible inputs, making it a versatile choice for interfacing with both CMOS and TTL logic levels.

This device features four identical 2-line to 1-line data selectors/multiplexers with 3-state outputs. It can pass data from either of its two inputs to the output, based on the state of the select input (S). When the output enable (OE) input is low, the device passes the selected data to the output. When OE is high, the output is in the high-impedance state, which is neither high nor low, allowing for the connection of multiple outputs to a common bus without interference.

With a wide operating temperature range of -40°C to 85°C, the SN74AHCT157PWR is suitable for a variety of applications in commercial and industrial environments. The device comes in a TSSOP (Thin Shrink Small Outline Package) with 16 pins, offering a compact footprint for space-constrained applications.

Key features of the SN74AHCT157PWR include:

• Wide operating voltage range of 4.5V to 5.5V
• High-speed, with typical tpd of 9 ns
• Low power consumption, with ICC of 20 µA maximum
• 4-bit data selector/multiplexer with 3-state outputs
• Inputs are TTL-voltage compatible
• Output drive capability of ±8 mA at 5V
• Operating temperature range of -40°C to 85°C
• 16-pin TSSOP package

Engineers and designers often utilize the SN74AHCT157PWR in digital systems that require data routing, signal gating, or the selection of multiple input sources to a single output line. Its high-speed performance, low power consumption, and compatibility with multiple logic families make it an excellent choice for a wide range of digital applications.

Whether you're designing data processing systems, communication interfaces, or need a reliable multiplexer for your digital logic circuits, the SN74AHCT157PWR from Texas Instruments is a robust, efficient solution that can meet your needs.
