Texas Instruments CD74HC541M96

Overview

CD74HC541M96 from Texas Instruments is a non-inverting octal buffer and line driver with three-state outputs, designed for bus interface and data routing in digital systems. It operates from 2 V to 6 V, delivers 15 LSTTL load drive capability, exhibits 9 ns typical propagation delay at 5 V/15 pF, and supports –55℃ to 125℃ industrial/military temperature range - enabling use in high-reliability embedded control and instrumentation buses.

For engineers reviewing the CD74HC541M96 datasheet, CD74HC541M96 pinout, CD74HC541M96 application, or CD74HC541M96 equivalent, key selection considerations include its non-inverting logic function, dual output-enable control (OE1/OE2), SOIC-20 package compatibility, wide supply voltage tolerance, and verified three-state bus-driving performance under extended temperature conditions.

Technical Context

The CD74HC541M96 implements eight independent non-inverting buffer channels, each with separate input and output terminals, and shares two global three-state output enable inputs (OE1, OE2) that operate OR-logic: either high forces all outputs into high-impedance mode. Its HC-series CMOS architecture ensures low static current (≤160 μA over full temperature range) and high noise immunity (NIL/NIH = 30% of VCC at 5 V).

It is functionally distinct from inverting variants (e.g., CD74HC540) and HCT-family parts (e.g., CD74HCT541), with voltage-level compatibility defined strictly for CMOS inputs (VIH ≥ 3.15 V at 4.5 V VCC) and TTL-load capable outputs (VOH ≥ 3.98 V at IOH = –6 mA, VOL ≤ 0.4 V at IOL = 6 mA).

FAQ

What is the logic function of CD74HC541M96?

CD74HC541M96 is a non-inverting octal buffer with three-state outputs. Each of its eight channels passes input A0–A7 to corresponding outputs Y0–Y7 without polarity inversion. Its dual output-enable inputs (OE1, OE2) operate with OR logic: either high forces all outputs into high-impedance mode. This behavior is confirmed in the truth table and functional description of the official TI datasheet SCHS189E.

What supply voltage range does CD74HC541M96 support?

CD74HC541M96 supports a supply voltage range of 2 V to 6 V, as specified in Section 5.2 "Recommended Operating Conditions" of the TI datasheet. This wide range enables interoperability between 3.3 V and 5 V subsystems without external level shifters and supports battery-backed operation down to 2 V, validated across the full –55℃ to 125℃ temperature range.

How does the three-state control work on CD74HC541M96?

CD74HC541M96 uses two active-low output-enable inputs, OE1 and OE2. As stated in Section 7.3 "Device Functional Modes", if either OE1 or OE2 is HIGH, all eight outputs (Y0–Y7) enter high-impedance state. For normal buffered output, both OE1 and OE2 must be LOW. This dual-enable structure provides flexible bus arbitration and is electrically distinct from single-OE alternatives like SN74HC244N.

What is the maximum output drive capability of CD74HC541M96?

CD74HC541M96 can drive up to 15 LSTTL loads, as explicitly stated in the Features section and Section 7.1 Overview of the TI datasheet. This corresponds to sourcing/sinking 6 mA per output while maintaining VOL ≤ 0.4 V and VOH ≥ 3.7 V at VCC = 4.5 V, enabling direct connection to legacy TTL buses without additional buffering stages.

Is CD74HC541M96 pin-compatible with CD74HCT541M96?

Yes, CD74HC541M96 is pin-compatible with CD74HCT541M96: both use identical SOIC-20 (DW) packaging, share identical pin numbering and terminal functions (A0–A7, Y0–Y7, OE1, OE2, VCC, GND), and are documented in the same datasheet (SCHS189E). However, they differ electrically - CD74HCT541M96 requires 4.5–5.5 V and accepts TTL-level inputs, whereas CD74HC541M96 operates from 2–6 V and requires CMOS-level inputs.
