Texas Instruments CD74ACT32M96

Overview

CD74ACT32M96 from Texas Instruments is a quadruple 2-input positive-OR gate IC in SOIC-14 package, operating at 4.5–5.5 V supply, delivering ±24 mA output drive, 3–12.1 ns propagation delay, and TTL-voltage-compatible inputs for digital logic interfacing in industrial control systems.

For engineers reviewing the CD74ACT32M96 datasheet, CD74ACT32M96 pinout, CD74ACT32M96 application, or CD74ACT32M96 equivalent, this page delivers verified functional identity, SOIC-14 pin mapping, OR-gate timing specs, ESD robustness (±2 kV HBM), and direct alternatives for logic-level translation and combinational logic design.

Technical Context

The CD74ACT32M96 implements four independent 2-input OR gates in a single CMOS device with buffered inputs, balanced tPLH/tPHL propagation delays, and SCR-latchup-resistant process architecture. It supports positive-logic Boolean Y = A + B across all gates with rail-to-rail output swing.

Designed for mixed-voltage system interfacing, it accepts TTL-level inputs (VIH = 2 V min, VIL = 0.8 V max) while operating from a 5-V CMOS supply, enabling seamless integration between legacy TTL and modern 5-V logic families without level-shifting circuitry.

FAQ

What logic function does the CD74ACT32M96 implement?

The CD74ACT32M96 implements four independent 2-input positive-OR gates, each performing Y = A + B in true-positive logic. All gates share common VCC and GND pins and operate simultaneously with matched propagation characteristics. Each gate's inputs and output are electrically isolated from others, allowing flexible routing in combinational logic networks.

Is CD74ACT32M96 pin-compatible with older CD74ACT32 variants?

Yes - CD74ACT32M96 uses the standard SOIC-14 (D package) footprint and identical pinout as CD74ACT32M, CD74ACT32M96G4, and CD74ACT32E (PDIP). Pin assignments for inputs (1A–4B), outputs (1Y–4Y), GND (7), VCC (14), and NC (8) are fully consistent across all CDx4ACT32 variants in D/N/J packages per TI's SCHS342A datasheet.

Can CD74ACT32M96 interface directly with 3.3-V microcontrollers?

CD74ACT32M96 inputs are TTL-voltage compatible (VIH ≥ 2.0 V, VIL ≤ 0.8 V), so they reliably recognize 3.3-V logic HIGH from most microcontrollers. However, its outputs swing rail-to-rail (0–5 V), requiring level translation if driving 3.3-V-only inputs. For bidirectional 3.3-V interfacing, add a resistor divider or dedicated level shifter on output lines.

What is the maximum capacitive load the CD74ACT32M96 can drive?

Per TI's switching characteristics table, CD74ACT32M96 is characterized at CL = 50 pF. While it can drive higher capacitance, propagation delay increases linearly - e.g., at 100 pF, tPLH/tPHL extends to ~15 ns. For >100 pF loads, verify timing margins in worst-case temperature/voltage corners using the device's Cpd = 47 pF and output impedance model.

Does CD74ACT32M96 require external pull-up or pull-down resistors on unused inputs?

Yes - all unused inputs of CD74ACT32M96 must be terminated to either VCC or GND to prevent floating nodes that cause increased ICC, erratic output states, or EMI. TI recommends tying unused inputs directly (not via resistors) to minimize leakage path uncertainty; resistor termination is acceptable only if value is ≤1 kΩ and layout avoids noise coupling.
