Product details
Overview
5962-9070201MEA from Texas Instruments is a military-grade quad 2-input non-inverting multiplexer (HCT type) in 16-lead CERDIP package, operating from 4.5 V to 5.5 V with -55 °C to +125 °C temperature range, 27 ns max propagation delay (CL = 50 pF, VCC = 4.5 V), and TTL-compatible inputs for use in radiation-tolerant avionics data routing.
For engineers reviewing the 5962-9070201MEA datasheet, 5962-9070201MEA pinout, 5962-9070201MEA application, or 5962-9070201MEA equivalent, key selection criteria include its QML-38534 Class V qualification, CERDIP hermetic packaging, enable-active-low logic, and guaranteed performance across extended military temperature extremes without derating.
Technical Context
The 5962-9070201MEA implements four independent 2:1 multiplexers sharing one common Select (S) input and one active-low Enable (E) input; outputs (1Y–4Y) are non-inverting and forced low when E is high. Its HCT logic family ensures direct compatibility with LSTTL input thresholds (VIL ≤ 0.8 V, VIH ≥ 2.0 V) while driving CMOS or TTL loads.
It uses silicon-gate CMOS technology with buffered inputs/outputs, balanced rise/fall times (15–22 ns typical), and low quiescent current (≤160 µA over full temperature range). Input leakage remains ≤±1 µA, and output drive capability is ±4 mA at VCC = 4.5 V with VOH ≥ 3.7 V and VOL ≤ 0.4 V under TTL load conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Pinout & Package
5962-9070201MEA is housed in a 16-lead CERDIP (Ceramic Dual In-line Package) with 0.3-inch body width and 0.1-inch lead pitch, rated for >10⁶ thermal cycles and compliant with MIL-STD-883 Method 2001.1 for hermeticity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1I0 | Data input A for channel 1 - connects to first source bus; referenced in truth table as I0 when S = L |
| 2 | 1I1 | Data input B for channel 1 - connects to second source bus; selected when S = H |
| 3 | 2I0 | Data input A for channel 2 - electrically isolated but shares S/E control with other channels |
| 4 | 2I1 | Data input B for channel 2 - supports parallel 4-bit data selection without additional control lines |
| 5 | 3I0 | Data input A for channel 3 - enables simultaneous routing of four independent bit-pairs |
| 6 | 3I1 | Data input B for channel 3 - maintains signal integrity via on-chip buffering and matched trace lengths |
| 7 | GND | Ground reference - must be connected to system chassis ground for EMI suppression and noise immunity |
| 8 | 4I0 | Data input A for channel 4 - completes quad-mux functionality for full byte-wide selection |
| 9 | 4I1 | Data input B for channel 4 - allows dual-bank register-to-bus transfer in microcoded controllers |
| 10 | VCC | Positive supply - requires local 0.1 µF ceramic decoupling within 1 cm of pin for stable switching |
| 11 | 4Y | Non-inverting output for channel 4 - asserted only when E = L; high-impedance state not supported |
| 12 | 3Y | Non-inverting output for channel 3 - synchronized to same S/E edges as other outputs (tPHL/tPLH matched) |
| 13 | 2Y | Non-inverting output for channel 2 - propagation delay variation ≤3 ns across all four channels |
| 14 | 1Y | Non-inverting output for channel 1 - used as primary data path in fault-tolerant voting logic |
| 15 | S | Common select input - controls all four muxes simultaneously; edge-rate insensitive due to Schmitt-trigger input |
| 16 | E | Active-low enable - forces all outputs low when high; critical for bus arbitration and power sequencing |

FAQ
What is the maximum operating frequency supported by the 5962-9070201MEA?
The 5962-9070201MEA does not specify a maximum clock frequency in its datasheet because it is a combinational logic device without internal clocking. Its usable data rate is determined by propagation delay: at VCC = 4.5 V and TA = 25 °C, tPLH/tPHL is 27 ns typical, supporting reliable operation up to ~15 MHz in cascaded logic paths with appropriate setup/hold margins. The 5962-9070201MEA maintains this performance across its full -55 °C to +125 °C range.
Is the 5962-9070201MEA pin-compatible with commercial-grade CD74HCT157 devices?
No - the 5962-9070201MEA uses a 16-lead CERDIP (J) package, whereas commercial CD74HCT157 variants use PDIP (N) or SOIC (D) packages with different pin pitches, body dimensions, and thermal characteristics. While logic function and pin functions match, PCB layout, soldering profile, and mechanical mounting are not interchangeable. The 5962-9070201MEA requires CERDIP-specific footprints and reflow profiles.
Does the 5962-9070201MEA support hot-swap or live-insertion?
No - the 5962-9070201MEA lacks hot-swap protection circuitry such as power-up sequencing control, I/O clamp diodes rated for back-drive conditions, or slew-rate limited outputs. Applying VCC or signal inputs before establishing proper GND connection risks latch-up or permanent damage due to uncontrolled current paths. System-level hot-swap must be implemented externally using dedicated power sequencers and bus isolators alongside the 5962-9070201MEA.
What is the meaning of "ME" and "A" in the 5962-9070201MEA part number?
In the 5962-9070201MEA designation, "ME" indicates the device meets MIL-PRF-38534 requirements for QML Class V (hermetic, tested to screening levels including burn-in and temperature cycling), while "A" denotes revision level A of the drawing specification. This full suffix distinguishes it from earlier revisions and confirms compliance with current DoD procurement standards. The 5962-9070201MEA is the official orderable number issued under the Defense Logistics Agency's Qualified Products List.
Can the 5962-9070201MEA be used with 3.3 V logic systems?
No - the 5962-9070201MEA is an HCT-family device specified only for 4.5 V to 5.5 V operation. At 3.3 V, input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V) become unreliable, propagation delays increase significantly beyond spec, and output drive falls below TTL-compatibility requirements. For 3.3 V systems, consider radiation-hardened alternatives like the RHFL157 or consult TI's space-grade 3.3 V logic portfolio; the 5962-9070201MEA must operate within its rated 4.5–5.5 V window.
