Texas Instruments CD74HC151M96

Overview

CD74HC151M96 from Texas Instruments is a high-speed CMOS 8-input digital multiplexer with complementary non-inverting (Y) and inverting (W) outputs, three binary select inputs (A/B/C), and active-low enable (G). It operates from 2 V to 6 V, supports -55°C to +125°C ambient temperature, and delivers propagation delays as low as 14 ns (typical at 4.5 V, 15 pF load) for data-to-output paths - used in address/data routing, signal selection, and logic function generation in industrial control and test equipment.

For engineers reviewing the CD74HC151M96 datasheet, CD74HC151M96 pinout, CD74HC151M96 application, or CD74HC151M96 equivalent, key selection criteria include its dual-output architecture, wide supply range, guaranteed operation across military-grade temperature extremes, and compatibility with LSTTL loads via buffered I/O - critical for legacy system upgrades and ruggedized embedded designs.

Technical Context

The CD74HC151M96 implements a single 8:1 multiplexer using standard HC logic architecture, where binary inputs A, B, and C decode one of eight data channels (D0–D7) to both Y (non-inverting) and W (inverting) outputs. Its enable input G is active-low and overrides all select logic when asserted.

All inputs and outputs are fully buffered, providing 10 LSTTL load fanout capability and balanced propagation delay (tpd ≤ 43 ns max at 4.5 V, -55°C to +125°C) with transition times under 22 ns. Input leakage remains ≤ ±1 μA, and power dissipation capacitance is specified at 59 pF for dynamic power estimation.

FAQ

What is the maximum supply voltage rating for CD74HC151M96?

The CD74HC151M96 has an absolute maximum supply voltage (VCC) of 7 V, but its recommended operating range is 2 V to 6 V. Operating continuously above 6 V risks permanent damage or accelerated parametric drift, even if within the absolute rating - always adhere to the 6 V upper limit for reliable long-term function of the CD74HC151M96.

Does CD74HC151M96 support true 3.3 V operation with guaranteed timing?

Yes, CD74HC151M96 is fully specified for 3.3 V operation: propagation delay is guaranteed ≤ 37 ns (max) at VCC = 3.3 V, TA = -55°C to +125°C, CL = 15 pF. All electrical characteristics including VIH/VIL, VOH/VOL, and ICC are validated across the full 2–6 V range - confirming robust 3.3 V interoperability for the CD74HC151M96.

Can CD74HC151M96 replace a 74LS151 in an existing design?

CD74HC151M96 can replace 74LS151 in most cases, but requires verification of supply voltage (LS uses 5 V only; HC supports 2–6 V) and input drive strength. While CD74HC151M96 accepts LS-compatible logic levels, its output drive (±4 mA) is lower than LS (±8 mA), so ensure connected loads do not exceed this limit - confirm compatibility before deploying CD74HC151M96.

What is the function of the W output on CD74HC151M96?

The W output on CD74HC151M96 is the inverted complement of the selected data input - if D3 is routed to Y (non-inverting output), then W delivers NOT(D3). This dual-output architecture eliminates external inverters in applications like parity generation, active-low enable logic, or differential signaling interfaces - a core functional feature of the CD74HC151M96.

Is CD74HC151M96 RoHS compliant and lead-free?

Yes, CD74HC151M96 is RoHS compliant with lead finish NIPDAU (nickel/palladium/gold) and moisture sensitivity level 1 (MSL-1), rated for peak reflow at 260°C. The "G4" suffix in variants like CD74HC151M96G4.A confirms TI's green packaging standard - fully compliant with EU RoHS Directive 2011/65/EU and JEDEC J-STD-020 - verified for the CD74HC151M96.
