Texas Instruments CD74ACT153M96

Overview

CD74ACT153M96 from Texas Instruments is a dual 4-line-to-1-line CMOS data selector/multiplexer with TTL-compatible inputs, ±24-mA output drive, balanced propagation delays (4.5–22 ns), and operation over –55°C to 125°C. It implements two independent 4:1 multiplexers sharing select lines A/B, each with dedicated strobe (G) control, used in digital logic routing, address/data path selection, and signal routing in industrial control and instrumentation systems.

For engineers reviewing the CD74ACT153M96 datasheet, CD74ACT153M96 pinout, CD74ACT153M96 application, or CD74ACT153M96 equivalent, key selection criteria include its dual-channel 4:1 configuration, SOIC-16 package, 4.5–5.5 V supply range, 24-mA drive strength, and MIL-STD-883-compliant ESD protection - all critical for high-reliability logic interface design.

Technical Context

The CD74ACT153M96 integrates two independent 4:1 multiplexer sections, each with separate strobe (G) inputs and shared binary select inputs A and B. Its internal architecture uses CMOS logic with bipolar-compatible speed and TTL-level input thresholds (VIH = 2 V, VIL = 0.8 V), enabling direct interfacing with legacy TTL systems without level-shifting.

Each section features AND-OR gate decoding driven by inverters and drivers, delivering rail-to-rail CMOS output swing. Propagation delays are tightly balanced across input types: tPLH/tPHL from select inputs (A/B) to output Y is 5.5–22 ns, from data inputs (C0–C3) is 4.5–18 ns, and from strobe (G) is 3.2–12.6 ns - ensuring deterministic timing in synchronous logic paths.

FAQ

What is the maximum clock/data rate supported by CD74ACT153M96?

The CD74ACT153M96 does not operate on a clock; it is combinational logic. Its usable data switching rate depends on propagation delay and load. With tPHL/tPLH ≤ 22 ns (max) into 50-pF loads, it reliably supports signal routing up to approximately 30 MHz in well-designed PCB layouts with proper termination and decoupling.

Does CD74ACT153M96 require external pull-up or pull-down resistors on unused inputs?

Yes. Per TI's SCBA004 application report, all unused inputs of CD74ACT153M96 must be tied to VCC or GND to prevent floating nodes that cause excessive ICC, oscillation, or ESD susceptibility. Inputs A, B, G, and any unconnected Cx lines fall under this requirement.

Can CD74ACT153M96 drive a 50-Ω transmission line directly?

Yes - the CD74ACT153M96 is specified to drive 50-Ω lines at 85°C (IOL = 50 mA, VOL ≤ 1.65 V at VCC = 5.5 V) and 75-Ω lines at 125°C. This capability is verified per the datasheet's footnote † and enables direct connection to impedance-controlled traces without external line drivers.

Is CD74ACT153M96 pin-compatible with CD74ACT153M?

Yes. CD74ACT153M96 and CD74ACT153M share identical SOIC-16 (D) packaging, pinout, electrical specifications, and marking (ACT153M). The "96" suffix denotes tape-and-reel packaging (2500 units), whereas "M" denotes tube packaging - functionally interchangeable in circuit design.

What is the power dissipation capacitance (Cpd) of CD74ACT153M96 and how is it used?

The CD74ACT153M96 has a typical power dissipation capacitance (Cpd) of 93 pF, as measured at 25°C. This value is used to estimate dynamic power consumption: Pdyn ≈ Cpd × VCC² × fswitch. For example, at 5 V and 10 MHz switching, dynamic power is ~23 mW - critical for thermal budgeting in dense logic assemblies.
