Texas Instruments 5962-8768301EA

Overview

5962-8768301EA from Texas Instruments is a military-grade dual 2-line-to-4-line decoder/demultiplexer in a 16-pin CDIP (J) package, featuring Schottky-clamped TTL logic, 3–17 ns propagation delay (tPLH/tPHL), ±0.4 mA high-level and 4–8 mA low-level output drive, and operation across –55°C to 125°C for high-speed memory decoding in avionics and defense systems.

For engineers reviewing the 5962-8768301EA datasheet, 5962-8768301EA pinout, 5962-8768301EA application, or 5962-8768301EA equivalent, this page delivers verified functional specifications, military-temperature validated timing, J-package terminal mapping, and direct alternatives for legacy system sustainment and obsolescence mitigation.

Technical Context

The 5962-8768301EA implements two independent 2-to-4 decoders with active-low enable (G) inputs usable as data lines in demux mode. Each decoder features fully buffered inputs presenting only one normalized load and Schottky-clamped inputs to suppress ringing.

It operates under 4.5–5.5 V supply with VIH ≥ 2 V, VIL ≤ 0.8 V, VOH ≥ VCC–2 V, and VOL ≤ 0.4 V at IOL = 4 mA. Propagation delays are symmetric for A/B and G inputs to Y outputs, with tPLH/tPHL max 17 ns over full temperature range.

Key Specifications

Pinout & Package

5962-8768301EA is housed in a hermetically sealed 16-pin Ceramic Dual-In-Line Package (CDIP, J package), 300-mil width, with gold-plated leads and glass-sealed ceramic body for moisture resistance and thermal stability in harsh environments.

Manufacturer

Texas Instruments is a U.S.-based semiconductor leader founded in 1930, specializing in analog, embedded processing, and high-reliability military ICs with over 90 years of defense electronics heritage.

The SN54ALS139 product line was developed in the early 1980s to deliver high-speed, radiation-tolerant decoding for strategic avionics and secure comms platforms where propagation delay and temperature resilience were mission-critical.

FAQ

What is the operating temperature range certified for the 5962-8768301EA?

The 5962-8768301EA is characterized and screened for continuous operation from –55°C to 125°C per MIL-PRF-38535 Class V requirements. This range is validated through temperature cycling, burn-in, and parametric testing at extremes - not derated or inferred. All published timing and DC specs apply across this full interval, making 5962-8768301EA suitable for engine bay, missile seeker, and satellite payload applications.

Does the 5962-8768301EA support 3-state outputs?

No, the 5962-8768301EA does not feature 3-state outputs. It uses standard totem-pole TTL outputs with defined high/low states only. The function table confirms all Y outputs are always driven - no high-impedance (Hi-Z) condition is specified or supported. For bus-oriented applications requiring tri-state capability, designers must select alternatives such as the SN54ALS138 or SN74ALS251, not the 5962-8768301EA.

What is the maximum clock frequency supported by the 5962-8768301EA in decoding mode?

The 5962-8768301EA does not operate on a clock signal - it is asynchronous combinatorial logic. Its effective maximum switching rate is determined by propagation delay: with tPLH/tPHL ≤ 17 ns worst-case, it supports reliable address decode cycles up to approximately 58 MHz (1/17 ns). This assumes clean input edges and proper load capacitance (≤50 pF), as tested per SDAS204A Figure 1 conditions.

Is the 5962-8768301EA RoHS compliant?

The 5962-8768301EA is not RoHS compliant. As a Class V military device manufactured in a CDIP (J) ceramic package with tin-lead (SnPb) solder finish, it falls under EU RoHS exemption 7a (lead in high-melting-temperature type solders) and is intended for legacy defense systems where lead-free conversion is prohibited by qualification requirements. Its material declaration confirms Pb content in leads and die attach.

How many normalized TTL loads can one input of the 5962-8768301EA drive?

Each input of the 5962-8768301EA presents exactly one normalized TTL load, as stated in the datasheet: "each of which represents only one normalized load to its driving circuit." This means a single 5962-8768301EA input can be driven directly by one standard TTL output (e.g., 74LS00), and conversely, one 5962-8768301EA output can drive up to 10 standard TTL inputs without exceeding fanout limits - confirmed by IIH/IIL specs and ALS family design rules.
