Nexperia USA Inc. 74HCT153PW,112

Overview

74HCT153PW,112 from NXP Semiconductors is a dual 4-to-1 CMOS multiplexer with TTL-compatible inputs, operating at 4.5–5.5 V supply, featuring propagation delay of 19 ns (max) at 5 V and output drive capability of ±4 mA. It is used in digital logic routing, address selection, and data path switching in industrial control modules.

For engineers reviewing the 74HCT153PW,112 datasheet, 74HCT153PW,112 pinout, 74HCT153PW,112 application, or 74HCT153PW,112 equivalent, key considerations include input compatibility with TTL logic levels, guaranteed high-speed switching across temperature range, and dual independent channel operation for compact bus management.

Technical Context

The 74HCT153PW,112 integrates two independent 4-input multiplexers sharing common select lines (S0, S1) and an active-low enable (E̅), each with separate outputs (Y0, Y1). It uses silicon-gate CMOS technology to achieve TTL-level input thresholds while maintaining low static power consumption.

All inputs are buffered with hysteresis for noise immunity, and outputs meet standard 74HCT drive specifications: VOH ≥ 4.4 V at IOH = –4 mA, VOL ≤ 0.4 V at IOL = 4 mA, ensuring reliable interfacing with legacy TTL and modern CMOS loads.

FAQ

Is 74HCT153PW,112 compatible with 3.3 V logic inputs?

No. The 74HCT153PW,112 requires 4.5–5.5 V supply and has TTL-compatible input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V), but its inputs are not 3.3 V tolerant. Driving it directly from 3.3 V logic risks undefined operation or damage due to input voltage exceeding VCC + 0.5 V absolute maximum rating.

What is the function of pin 8 (E̅) on the 74HCT153PW,112?

Pin 8 is the active-low enable input (E̅). When E̅ = HIGH, both outputs (Y0 and Y1) are forced LOW regardless of select or input states. When E̅ = LOW, the multiplexers operate normally, routing selected inputs to their respective outputs based on S0/S1 state.

Can 74HCT153PW,112 be used as a 1-of-8 decoder?

No. The 74HCT153PW,112 is strictly a dual 4-to-1 multiplexer with no built-in decoding logic. It lacks enable decoding for 3-bit address inputs and does not generate active-HIGH decoded outputs. A dedicated 74HCT138 or similar 3-to-8 decoder is required for that function.

Does 74HCT153PW,112 have Schmitt-trigger inputs?

No. The 74HCT153PW,112 uses standard CMOS input buffers without hysteresis. While some NXP HCT devices include Schmitt-trigger variants (e.g., 74HCT14), the 74HCT153PW,112 datasheet specifies no input hysteresis-its inputs respond to monotonic voltage transitions at defined TTL thresholds.
