Product details
Overview
5962-8974501EA from Texas Instruments is a high-speed CMOS 3-to-8 line decoder/demultiplexer with non-inverting outputs, designed for military-grade memory address decoding and data routing. It features three binary select inputs (A0–A2), two active-low enables (E1̅, E2̅), one active-high enable (E3), operates from -55°C to +125°C, and delivers 13 ns typical propagation delay at VCC = 5 V, CL = 15 pF.
For engineers reviewing the 5962-8974501EA datasheet, 5962-8974501EA pinout, 5962-8974501EA application, or 5962-8974501EA equivalent, this device serves as a radiation-tolerant, high-reliability logic decoder in avionics, spaceflight control systems, and hardened embedded controllers requiring wide-temperature operation and LSTTL-compatible drive capability.
Technical Context
The 5962-8974501EA implements a silicon-gate CMOS architecture optimized for low power consumption while matching LSTTL speed performance. Its truth table defines active-high output behavior: when enabled, exactly one of eight outputs (Y0–Y7) transitions high based on A2:A0 address inputs - contrasting with the inverting 138-series.
Three enable inputs (E1̅, E2̅, E3) support hierarchical cascading in large address spaces; all outputs are buffered CMOS with 10 LSTTL load fanout capability and balanced tPLH/tPHL timing across temperature extremes (-55°C to +125°C).

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD54HC238F3A | Same function, HC logic family (2 V–6 V operation); not radiation-hardened or MIL-qualified | Commercial/industrial use only; lacks DSCC certification and extended burn-in screening | Select for cost-sensitive terrestrial designs where radiation tolerance is unnecessary |
| 5962-8688401EA | Inverting-output variant (138-type); identical package, temperature range, and MIL-PRF-38535 Class V qualification | Requires inverted address logic or external inverters when interfacing to active-high peripherals | Select when system architecture already uses inverting decode logic or shares enable networks with 138-family devices |
Compared with CD54HC238F3A and 5962-8688401EA, the 5962-8974501EA uniquely combines non-inverting output behavior with full MIL-PRF-38535 Class V qualification - making it the only drop-in solution for radiation-hardened systems requiring active-high enable assertion without redesign.

FAQ
What is the logic family and voltage compatibility of the 5962-8974501EA?
The 5962-8974501EA belongs to the HCT (High-Speed CMOS TTL-compatible) logic family and operates strictly within 4.5 V to 5.5 V. It accepts LSTTL input levels (VIH ≥ 2.0 V, VIL ≤ 0.8 V), ensuring seamless integration into legacy 5 V systems without level shifters. This specification is confirmed in the TI datasheet SCHS147E and applies directly to the 5962-8974501EA variant.
Does the 5962-8974501EA support cascading with other decoders?
Yes, the 5962-8974501EA supports cascading via three dedicated enable inputs: two active-low (E1̅, E2̅) and one active-high (E3). This triple-enable architecture allows hierarchical decoding of larger address spaces - for example, using one 5962-8974501EA to select among eight groups, each controlled by another 5962-8974501EA. The design is validated in the truth table and functional diagram of SCHS147E.
What is the maximum fanout capability of the 5962-8974501EA outputs?
The 5962-8974501EA outputs drive up to 10 LSTTL loads over its full -55°C to +125°C operating range. This fanout rating is specified in the "Fanout (Over Temperature Range)" section of the datasheet and reflects worst-case drive strength under extreme thermal conditions - critical for reliability in aerospace deployments where thermal margin is non-negotiable.
Is the 5962-8974501EA radiation-hardened or MIL-qualified?
Yes, the 5962-8974501EA is a Class V device per MIL-PRF-38535, manufactured to DSCC drawing 5962-8974501EA and screened for radiation hardness, hermeticity, and extended temperature operation. Its qualification includes burn-in, temperature cycling, and radiation testing - distinguishing it from commercial variants like CD54HC238F3A, which lack these certifications.
How does the 5962-8974501EA differ from the 5962-8688401EA?
The 5962-8974501EA is the non-inverting (238-type) decoder, while the 5962-8688401EA is the inverting (138-type) version. Both share identical packaging (16-lead CERDIP), temperature range (-55°C to +125°C), and MIL-PRF-38535 Class V qualification. Their truth tables and output polarities are complementary - a key distinction affecting system-level logic design and peripheral interface requirements.
