Nexperia USA Inc. 74HC151PW-Q100,118

Overview

74HC151PW-Q100 from Nexperia is an automotive-grade 8-input CMOS multiplexer with complementary outputs (Y and Y), three binary select inputs (S0–S2), and active-low enable (E). It operates from 2.0 V to 6.0 V, supports -40 °C to +125 °C ambient range, and delivers propagation delays as low as 15 ns at VCC = 6.0 V. It routes one of eight data inputs to Y/Y based on select code, used in signal routing and data path selection within automotive body control modules.

For engineers reviewing the 74HC151PW-Q100 datasheet, 74HC151PW-Q100 pinout, 74HC151PW-Q100 application, or 74HC151PW-Q100 equivalent, key selection criteria include its AEC-Q100 Grade 1 qualification, TTL-compatible 74HCT variant option, TSSOP16 package with side-wettable flanks for AOI, and verified performance under automotive thermal and ESD stress conditions.

Technical Context

This device implements a standard 3-to-8 binary decoder-driven analog switch matrix, where S0–S2 determine which of I0–I7 appears at Y (non-inverting) and Y (inverting). The enable input E forces both outputs to fixed logic states (Y = LOW, Y = HIGH) when asserted, providing clean bus isolation.

It uses silicon-gate CMOS technology for low static current (≤160 μA at 125 °C), high noise immunity (>40% VCC), and latch-up immunity exceeding 100 mA per JESD78 Class II Level B. Input clamp diodes allow safe interfacing to voltages beyond VCC when used with current-limiting resistors.

FAQ

What is the maximum clock frequency supported by the 74HC151PW-Q100?

The 74HC151PW-Q100 is not a clocked sequential device-it has no internal clock and operates asynchronously. Its usable data rate depends on propagation delay and load capacitance: with CL = 50 pF and VCC = 6.0 V, maximum toggle rate is ~20 MHz (based on tpd = 15 ns and tt = 13 ns). For reliable operation, input signal transitions must meet minimum rise/fall rate specs (≥83 ns/V at VCC = 6.0 V).

Can the 74HC151PW-Q100 be used with 3.3 V microcontrollers?

Yes-its 2.0 V to 6.0 V supply range and CMOS input thresholds make it fully compatible with 3.3 V systems. At VCC = 3.3 V, VIH = 2.31 V (70% of VCC) and VIL = 0.99 V (30% of VCC), ensuring robust noise margins against typical 3.3 V GPIO outputs. Output VOH exceeds 3.0 V at IO = –4 mA, safely driving downstream 3.3 V logic.

Does the Y output mirror the selected input exactly, including timing?

Yes-Y is the non-inverted, buffered replica of the selected input (I0–I7), with propagation delay matching the In→Y path (e.g., 15 ns max at VCC = 6.0 V). Y is its exact logical complement, with matched delay (In→Y adds ≤2 ns skew vs. In→Y), enabling true differential routing for noise rejection in sensitive analog-digital interfaces.

Is the TSSOP16 package (SOT403-1) lead-free and RoHS compliant?

Yes-the 74HC151PW-Q100 uses a lead-free, halogen-free, RoHS-compliant TSSOP16 package (SOT403-1) with matte-tin termination finish. It meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL1) and is qualified for reflow soldering per IPC/JEDEC J-STD-020 Rev. E, with peak temperature up to 260 °C.
