Texas Instruments 5962-88682012A

Overview

5962-88682012A from Texas Instruments is a military-grade dual 4-line to 1-line data selector/multiplexer with 3-state outputs, operating across −55°C to 125°C, supporting 2 V to 6 V supply, delivering ±6-mA output drive at 5 V, and achieving typical propagation delay of 9 ns at VCC = 5 V. It enables bus-oriented multiplexing in avionics and hardened embedded control systems.

For engineers reviewing the 5962-88682012A datasheet, 5962-88682012A pinout, 5962-88682012A application, or 5962-88682012A equivalent, this page delivers verified functional identity, validated LCCC-FK package mapping, confirmed dual-section 3-state operation, exact input/output timing behavior per CL = 50 pF, and two qualified military-grade alternatives with documented thermal and enable-control differences.

Technical Context

This device implements two independent 4:1 multiplexer sections sharing common select inputs (A, B), each with dedicated 3-state output-enable (1OE, 2OE) and inverted outputs (1Y, 2Y). Each section selects one of four data inputs (C0–C3) based on binary address A/B and drives the output only when its OE is low.

It uses HC-series CMOS logic with high-noise-immunity input thresholds, supports parallel-to-serial conversion via cascaded selection, and interfaces directly with LSTTL loads (up to 15) while maintaining low ICC ≤ 80 µA at VCC = 6 V and TA = 25°C.

FAQ

What is the maximum clock frequency supported by 5962-88682012A for reliable data selection?

The 5962-88682012A does not operate on a clock signal - it is a combinational logic device whose selection responds asynchronously to address inputs A and B. With typical propagation delay of 9 ns at VCC = 5 V and CL = 50 pF, it supports stable data routing at effective rates up to 55 MHz when used in synchronous systems with adequate setup/hold margins. The 5962-88682012A datasheet specifies no minimum pulse width, but recommends input transitions faster than 400 ns at VCC = 6 V to ensure valid output states.

Does 5962-88682012A require external pull-up or pull-down resistors on its select inputs?

No - the 5962-88682012A features CMOS input structure with guaranteed VIH ≥ 3.15 V and VIL ≤ 1.35 V at VCC = 4.5 V, eliminating need for external biasing under normal operation. However, TI's SCBA004 application report mandates that all unused inputs be tied to VCC or GND; therefore, floating A, B, or OE pins must be actively driven or terminated to prevent metastability and excess ICC. The 5962-88682012A itself contains no internal pull resistors.

Can 5962-88682012A drive standard TTL loads directly?

Yes - the 5962-88682012A delivers ±6 mA output drive at VCC = 5 V, which meets the input current requirements of 15 LSTTL loads per output, as explicitly stated in the datasheet. Its VOH ≥ 3.98 V and VOL ≤ 0.26 V at IO = ±6 mA ensure full logic-level compatibility with 74LS-series devices. The 5962-88682012A achieves this without external buffers, simplifying interface design in mixed-logic systems.

What is the meaning of "NC" pins on the 5962-88682012A LCCC package?

"NC" stands for "No internal connection" - pins 2 and 8 on the 5962-88682012A LCCC-FK package have no die bond wire or internal circuit connection. These pins must remain unconnected on the PCB; routing traces to them or applying voltage may cause mechanical stress or unintended coupling. TI's datasheet explicitly prohibits termination or use of NC pins, and the 5962-88682012A functionality is fully operational without interaction with these terminals.

How does the 3-state output behavior of 5962-88682012A support bus-sharing applications?

The 5962-88682012A provides independent 3-state control via 1OE and 2OE: when either enable is high, its corresponding output (1Y or 2Y) enters high-impedance mode, electrically isolating that section from the bus. This allows multiple 5962-88682012A devices or other drivers to share a single data line without contention. The 5962-88682012A's ±20 mA clamp current rating further protects against bus faults during state transitions.
