Texas Instruments CD74ACT541M96

Overview

CD74ACT541M96 from Texas Instruments is a non-inverting octal 3-state buffer/line driver in SOIC-20 package, operating at 4.5–5.5 V supply, delivering ±24 mA output drive per pin with balanced propagation delays (tPLH/tPHL ≤ 7.5 ns at 5 V), and supporting 50-Ω transmission-line driving for industrial bus interface applications.

For engineers reviewing the CD74ACT541M96 datasheet, CD74ACT541M96 pinout, CD74ACT541M96 application, or CD74ACT541M96 equivalent, key selection criteria include 3-state enable timing (tPZL/tPLZ ≤ 12.2 ns), TTL-compatible input thresholds (VIH = 2 V, VIL = 0.8 V), low quiescent current (ICC ≤ 160 µA), and −55°C to +125°C extended temperature operation.

Technical Context

The CD74ACT541M96 implements two active-low 3-state output enables (OE1, OE2) controlling eight non-inverting outputs simultaneously, with SCR-latchup-resistant Advanced CMOS process ensuring robustness in noisy environments. Its ACT-series logic family guarantees TTL-compatible input levels and fast switching across full military-grade temperature range.

Propagation delay symmetry (tPLH ≈ tPHL) and low-output-capacitance design (CO = 15 pF) minimize signal skew and ground bounce during high-speed bus driving. The device supports fanout to 15 FAST® ICs and meets JEDEC JESD78 Class II latch-up immunity.

FAQ

What is the maximum operating frequency supported by CD74ACT541M96?

The CD74ACT541M96 does not specify a maximum clock frequency, as it is a combinational buffer-not a clocked device. Its 7.5 ns maximum propagation delay at 5 V enables reliable use in digital buses operating up to approximately 100 MHz, assuming adequate setup/hold margins and controlled trace impedance. Actual system frequency depends on board layout, loading, and timing budget allocation.

Does CD74ACT541M96 support mixed-voltage operation (e.g., 3.3-V inputs with 5-V supply)?

Yes, CD74ACT541M96 accepts 3.3-V logic-high inputs while powered at 5 V: its VIH threshold is 2.0 V (min), well below 3.3 V, and input structures tolerate VI up to VCC. However, outputs swing rail-to-rail (0 V to 5 V), so downstream 3.3-V receivers require level-shifting or tolerance to 5-V signals.

Can CD74ACT541M96 drive multiple 50-Ω transmission lines simultaneously?

Yes, CD74ACT541M96 is explicitly characterized for 50-Ω transmission-line driving at +85°C and +125°C per TI datasheet Section 4.5–4.6. Each output delivers ±24 mA, meeting the current requirement for a single 50-Ω line (±100 mA peak for 5 V swing). Driving multiple lines concurrently requires verifying total ICC and thermal limits.

What is the meaning of "M96" in CD74ACT541M96?

The "M96" suffix denotes Texas Instruments' standard SOIC-20 package (DW) supplied in large tape-and-reel format: 2000 units per reel, RoHS-compliant NiPdAu lead finish, MSL Level-1 rating (unlimited floor life), and Q1 pin-1 orientation. It distinguishes this production version from tube-packaged variants (e.g., CD74ACT541E) or obsolete variants.

Is CD74ACT541M96 pin-compatible with CD74AC541M96?

Yes, CD74ACT541M96 and CD74AC541M96 share identical 20-pin SOIC (DW) footprints, pin functions, and truth tables. However, they differ electrically: CD74ACT541M96 operates only at 4.5–5.5 V with TTL-compatible inputs, while CD74AC541M96 supports 1.5–5.5 V but has AC-series input thresholds. Direct substitution requires verifying supply voltage and interface logic levels.
