Texas Instruments CD74HC75M96

Overview

CD74HC75M96 from Texas Instruments is a dual 2-bit bistable transparent latch IC with true/complementary outputs, buffered I/O, and operation across -55°C to +125°C. It features separate active-low enable inputs (1E, 2E), 2V–6V supply range, and propagation delays as low as 19 ns (VCC = 6V, CL = 50 pF). It is used in industrial control logic, data routing in test equipment, and high-reliability hold-register applications.

For engineers reviewing the CD74HC75M96 datasheet, CD74HC75M96 pinout, CD74HC75M96 application, or CD74HC75M96 equivalent, this page delivers verified functional identity, SOIC-16 package mapping, latch timing behavior, input compatibility, and validated alternative options for dual 2-bit transparent latch designs.

Technical Context

The CD74HC75M96 implements two independent 2-bit transparent latches, each with dedicated active-low enable (1E/2E) controlling data flow from D0/D1 to Q0/Q1 and their complements. Its HC logic family ensures CMOS-level noise immunity (NIL/NIH = 30% of VCC at 5V) and rail-to-rail output swing.

It operates over full military temperature range (-55°C to +125°C) with supply voltage flexibility (2V–6V), enabling use in wide-input-voltage systems. Propagation delay is balanced between rising/falling edges, and transition times are tightly controlled (e.g., 13 ns max tTLH/tTHL at 6V, CL = 50 pF).

FAQ

What is the exact logic function of CD74HC75M96?

CD74HC75M96 is a dual 2-bit bistable transparent latch with independent active-low enable inputs (1E and 2E). When an enable is HIGH, its corresponding D0/D1 inputs pass directly to Q0/Q1 outputs; when LOW, outputs retain their last latched state. It provides true outputs only - complementary outputs require external inversion or use of the companion CD74HC75 with explicit Q̅ pins.

Does CD74HC75M96 support 3.3V operation?

Yes, CD74HC75M96 fully supports 3.3V operation within its specified 2V–6V supply range. At VCC = 3.3V, VIH(min) = 2.31V and VIL(max) = 1.0V per HC specifications, ensuring reliable interfacing with standard 3.3V CMOS logic families without level translation.

What is the maximum clock/data frequency supported by CD74HC75M96?

CD74HC75M96 does not operate on a clock; it is edge-triggered only by enable transitions. Its usable data rate depends on enable pulse width (tW ≥ 20 ns min at 4.5V) and setup/hold timing (tSU = 15 ns, tH = 3 ns). With proper timing margins, it reliably handles data valid windows up to ~25 MHz in enable-gated applications.

Is CD74HC75M96 pin-compatible with CD74HCT75M96?

No - CD74HC75M96 and CD74HCT75M96 share identical pinout and package (SOIC-16), but differ electrically: HC uses 2V–6V supply and CMOS input thresholds, while HCT requires 4.5V–5.5V and accepts TTL-level inputs (VIH = 2.0V min). They are not functionally interchangeable without verifying supply and driver compatibility.

What does the "96" suffix mean in CD74HC75M96?

The "96" suffix in CD74HC75M96 indicates tape-and-reel packaging: 2500 units per large reel (TI SPQ = 2500), RoHS-compliant, with MSL Level-1 rating. This distinguishes it from tube-packaged variants like CD74HC75M (SPQ = 40) and supports automated SMT assembly lines.
