Texas Instruments 5962-9758301Q2A

Overview

5962-9758301Q2A from Texas Instruments is a dual 4-line to 1-line data selector/multiplexer with independent strobe inputs, operating across −55°C to 125°C, featuring 20-pin LCCC (FK) package, propagation delays as low as 1.7 ns (tPHL, C→Y), and TTL-compatible input/output levels. It performs parallel-to-serial conversion in military-grade digital control systems requiring cascaded signal routing.

For engineers reviewing the 5962-9758301Q2A datasheet, 5962-9758301Q2A pinout, 5962-9758301Q2A application, or 5962-9758301Q2A equivalent, key selection criteria include its dual-section architecture with shared select lines A/B, separate 1G/2G enable controls, −55°C to 125°C operation, LCCC FK package thermal robustness, and verified 20 mA low-level output drive capability.

Technical Context

The 5962-9758301Q2A implements two independent 4:1 multiplexer sections sharing binary select inputs A and B, each with dedicated strobe (G) control enabling cascading without external logic. Each section routes one of four data inputs (C0–C3) to its output (1Y or 2Y) based on A/B state when its strobe is active low.

It uses standard TTL circuitry with inverters and drivers feeding AND-OR gates for full binary decoding. Input clamp current is rated at −18 mA, and outputs support 20 mA sink current at VOL ≤ 0.5 V under recommended conditions (VCC = 4.5 V to 5.5 V).

Key Specifications

Pinout & Package

5962-9758301Q2A is housed in a 20-pin Leadless Ceramic Chip Carrier (LCCC), FK package - a hermetic, surface-mount ceramic package with J-lead geometry, optimized for high-reliability military and aerospace applications where moisture resistance and thermal cycling stability are critical.

FAQ

What is the operating temperature range of the 5962-9758301Q2A?

The 5962-9758301Q2A is characterized for continuous operation from −55°C to 125°C. This full military temperature range is validated per MIL-STD-883 test methods and applies to all electrical parameters in the datasheet, including propagation delay, VOL, and IOL. The 5962-9758301Q2A maintains guaranteed performance across this range without derating, making it suitable for engine-mounted or space-exposed electronics where thermal extremes are routine.

Does the 5962-9758301Q2A support cascading with other multiplexers?

Yes, the 5962-9758301Q2A supports cascading via its dedicated strobe inputs (1G and 2G). When multiple 5962-9758301Q2A devices are used, their strobes can be wired in series or controlled by a common timing signal to enable sequential data routing - for example, selecting one of eight inputs using two 5962-9758301Q2A units. The datasheet explicitly confirms this capability under "Strobe (Enable) Line Provided for Cascading (N Lines to N Lines)".

What package type is used for the 5962-9758301Q2A?

The 5962-9758301Q2A uses a 20-pin Leadless Ceramic Chip Carrier (LCCC) with FK package drawing. This hermetically sealed ceramic package features J-leads, zero lead protrusion, and is qualified to MIL-PRF-38534 Class K. Its dimensions, thermal characteristics, and solder profile are documented in TI's Package Option Addendum, and it is distinct from the 16-pin CDIP (J) or CFP (W) variants of the same logic function.

How many data inputs does the 5962-9758301Q2A support?

The 5962-9758301Q2A supports eight total data inputs - four per section (1C0–1C3 and 2C0–2C3). Each of its two independent 4:1 multiplexer sections accepts four digital inputs and routes one to its respective output (1Y or 2Y) based on the shared A/B select lines and individual strobe state. No external decoding logic is required to access all eight inputs.

Is the 5962-9758301Q2A pin-compatible with commercial SN74F153 variants?

No, the 5962-9758301Q2A is not pin-compatible with commercial SN74F153 variants. It uses a 20-pin LCCC (FK) package, whereas SN74F153 parts use 16-pin packages (D, N, or NS). Pin counts, layouts, and terminal functions differ fundamentally - for example, the 5962-9758301Q2A includes four NC pins and separates VCC/GND across corners, unlike the 16-pin DIP/SOIC footprints. Direct replacement requires PCB redesign.
