Product details
Overview
CD54AC153F3A from Texas Instruments is a military-grade dual 4-line to 1-line data selector/multiplexer in 16-pin CDIP (J) package, operating from 1.5 V to 5.5 V with ±24 mA output drive, balanced propagation delays, and 2 kV HBM ESD rating. It implements two independent 4:1 multiplexers with separate active-low strobe inputs (1G, 2G), address inputs A/B shared between channels, and supports high-reliability data routing in aerospace and defense timing and control systems.
For engineers reviewing the CD54AC153F3A datasheet, CD54AC153F3A pinout, CD54AC153F3A application, or CD54AC153F3A equivalent, this page delivers verified electrical specs (tPLH/tPHL down to 5 ns at 5 V), thermal metrics (RθJA = 67 °C/W), noise-immune CMOS operation, SCR-latchup resistance, and precise pin-function mapping for layout validation and MIL-STD-883-compliant design integration.
Technical Context
The CD54AC153F3A integrates two independent 4:1 multiplexer sections, each with dedicated active-low strobe (1G/2G), shared binary address inputs (A, B), four data inputs (C0–C3 per channel), and one output (1Y/2Y). Its logic diagram confirms positive-logic decoding via inverters and AND-OR gates, enabling full binary selection without external decoding logic.
It uses SCR-latchup-resistant CMOS process technology and meets MIL-STD-883 requirements for temperature range (−55°C to +125°C), supply voltage (1.5 V to 5.5 V), and ESD immunity (±2000 V HBM). Propagation delay balance across channels and input-to-output paths ensures deterministic timing in synchronous data switching applications.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 4:1 multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD74AC153E | Commercial-grade PDIP variant; same logic function, pinout, and AC specs but rated −40°C to +85°C and RoHS-compliant (NIPDAU) | Suitable for industrial control and non-military embedded systems; lacks MIL-STD-883 qualification and extended temperature range | Select CD74AC153E for cost-sensitive commercial designs where military temp range and hermetic packaging are unnecessary |
| CD74AC153M96 | SOIC-16 package with same electrical specs; RoHS-compliant, tape-and-reel delivery, MSL Level-1 rating | Preferred for automated SMT assembly and space-constrained PCBs; not suitable for through-hole or high-vibration environments | Choose CD74AC153M96 when surface-mount manufacturing, reflow compatibility, and smaller footprint outweigh hermeticity needs |
Compared with CD54AC153F3A, CD74AC153E offers lower cost and RoHS compliance but sacrifices extended temperature and military qualification, while CD74AC153M96 enables modern SMT production yet lacks the ruggedized CDIP package and −55°C capability required for airborne platforms.

FAQ
What is the maximum operating temperature for CD54AC153F3A?
The CD54AC153F3A is fully specified and qualified for continuous operation from −55°C to +125°C, meeting MIL-STD-883 temperature testing requirements. This extended range is enabled by its ceramic DIP (CDIP) package and SCR-latchup-resistant CMOS process, making it suitable for engine-mounted avionics and space-constrained military chassis where ambient temperatures exceed commercial limits. The CD54AC153F3A maintains full functionality-including propagation delay, output drive, and noise immunity-across this entire range.
Does CD54AC153F3A support 3.3 V logic levels?
Yes, CD54AC153F3A fully supports 3.3 V operation with guaranteed performance: at VCC = 3.3 V ± 0.3 V, it delivers tPLH/tPHL ≤ 25.5 ns (−40°C to +85°C) and ≥2.4 V VOH at −4 mA load. Its input thresholds scale with VCC (VIH = 2.1 V, VIL = 0.9 V), ensuring clean interfacing with 3.3 V microcontrollers and FPGAs. The CD54AC153F3A also maintains 30% noise immunity margin and ±24 mA drive capability at this voltage, preserving signal integrity in mixed-voltage systems.
Is CD54AC153F3A pin-compatible with CD74AC153 variants?
Yes, CD54AC153F3A is functionally and pinout-compatible with CD74AC153E (PDIP), CD74AC153M96 (SOIC), and CD74AC153PWR (TSSOP) - all share identical pin numbering, signal names, and logic behavior per TI's SCHS334C datasheet. However, mechanical dimensions, thermal resistance (e.g., RθJA = 67 °C/W for CD54AC153F3A vs. 119.9 °C/W for SOIC), and qualification level differ. The CD54AC153F3A retains the same 16-pin layout but requires through-hole mounting and handles higher thermal stress due to its ceramic construction.
What is the purpose of the separate strobe inputs (1G and 2G) on CD54AC153F3A?
The separate active-low strobe inputs (1G and 2G) on CD54AC153F3A allow independent enable/disable control of each 4:1 multiplexer section. When 1G is low, Channel 1 outputs the selected C0–C3 input based on A/B address; when high, 1Y is forced high-impedance (not high-level). This enables time-multiplexed or conditional routing-for example, using 1G to gate sensor data only during valid sampling windows while holding 2G low to continuously monitor a reference signal. The CD54AC153F3A thus supports asynchronous channel arbitration without external logic.
How does CD54AC153F3A handle unused inputs in a system design?
All unused inputs on CD54AC153F3A-including address lines A/B, strobes 1G/2G, and data inputs C0–C3-must be tied to a defined logic level (VCC or GND) per TI's SCBA004 guidance. Floating inputs cause undefined states, increased ICC current, and potential oscillation due to CMOS input structure. For example, an unused 2G should be pulled high (to VCC) to disable Channel 2, while unused C1/C2 on Channel 1 may be tied to GND. The CD54AC153F3A's SCR-latchup-resistant design tolerates such static biasing without degradation, ensuring long-term reliability in fielded systems.
