Texas Instruments 5962-9750801QEA

Overview

5962-9750801QEA from Texas Instruments is a military-grade dual 2-line-to-4-line decoder/demultiplexer in a 16-pin CDIP package, featuring TTL-compatible inputs, active-low enable (G̅), and complementary active-high/active-low outputs (Y₀–Y₃ and Y̅₀–Y̅₃). It operates across –55°C to +125°C, supports 100% tested DC parameters per MIL-STD-883, and is used in radiation-tolerant avionics control logic.

For engineers reviewing the 5962-9750801QEA datasheet, 5962-9750801QEA pinout, 5962-9750801QEA application, or 5962-9750801QEA equivalent, this device serves as a QML-qualified logic building block for dual independent decoding paths with guaranteed timing and latch-up immunity in harsh-environment digital systems.

Technical Context

This device integrates two identical 2-to-4 line decoders on a single die, each with separate address inputs (A₀, A₁), common active-low enable (G̅), and fully decoded outputs. Each decoder drives four active-high outputs (Y₀–Y₃) and their complements (Y̅₀–Y̅₃) simultaneously.

It implements standard TTL logic thresholds (V_IH = 2.0 V min, V_IL = 0.8 V max), guarantees t_PLH/t_PHL ≤ 25 ns at V_CC = 5 V, and meets MIL-PRF-38535 Class V requirements for screening, burn-in, and lot acceptance testing.

FAQ

What is the operating voltage range for the 5962-9750801QEA?

The 5962-9750801QEA operates over a supply voltage range of 4.5 V to 5.5 V. This range ensures compatibility with standard 5 V military power buses and accommodates allowable ripple and droop under load. All electrical specifications-including propagation delay, output drive, and noise margins-are guaranteed across this full range at temperatures from –55°C to +125°C. The 5962-9750801QEA maintains LS-TTL logic thresholds throughout this window.

Does the 5962-9750801QEA support wired-OR expansion with other decoders?

Yes, the 5962-9750801QEA supports wired-OR expansion via its active-low enable (G̅) input and complementary outputs. Multiple 5962-9750801QEA devices can be cascaded by connecting G̅ to decoded outputs of a higher-order decoder, enabling 3-to-8 or 4-to-16 expansion without external gates. Its TTL-compatible inputs accept standard logic levels, and its outputs drive standard TTL loads directly.

How does the 5962-9750801QEA differ from commercial SN74LS155A variants?

The 5962-9750801QEA is a QML-38535 Class V qualified version with full MIL-STD-883 testing, hermetic CDIP packaging, and operation from –55°C to +125°C. Commercial SN74LS155A parts use plastic packages, operate only from 0°C to 70°C, and lack radiation hardness or burn-in screening. The 5962-9750801QEA die is identical, but its qualification and packaging make it suitable for flight hardware where reliability is non-negotiable.

Is the 5962-9750801QEA pin-compatible with SN54LS155A or SNJ54LS155AJ?

Yes, the 5962-9750801QEA is pin-compatible with SN54LS155A and SNJ54LS155AJ - all use the same 16-pin CDIP (J) package, identical pinout, and share identical logic functionality and timing. Differences lie solely in part numbering, marking, and documentation traceability; electrical and mechanical interchangeability is confirmed per TI's packaging addendum and SDLS057 datasheet revision history.

What is the maximum clock frequency supported by the 5962-9750801QEA?

The 5962-9750801QEA is not a clocked device and has no maximum clock frequency rating. As a combinational decoder, its usable input transition rate depends on propagation delay (≤25 ns) and system setup/hold timing. In practice, it reliably supports address/data strobe rates up to ~20 MHz in synchronous systems, limited by board-level signal integrity-not internal device bandwidth. The 5962-9750801QEA performs static decoding with no internal latching or clock dependency.
