Product details

Overview

8500101EA from Texas Instruments is a military-grade hex noninverting buffer/line driver with dual 3-state enable inputs (OE1, OE2), designed for high-density bus interfacing and memory address driving in harsh-environment systems. It operates from 2 V to 6 V, delivers ±6-mA output drive at 5 V, exhibits typical propagation delay of 10 ns, and draws ≤80 µA ICC - enabling low-power, high-current bus control in avionics and defense electronics.

For engineers reviewing the 8500101EA datasheet, 8500101EA pinout, 8500101EA application, or 8500101EA equivalent, key selection criteria include its CDIP-J package, −55°C to +125°C operating range, dual-gated 3-state architecture, and compatibility with LSTTL load driving (up to 15 units) without level-shifting.

Technical Context

The 8500101EA implements six independent CMOS buffer channels, each with true (noninverting) logic and dual active-low output-enable controls. Its dual-OE architecture allows granular channel gating: outputs enter high-impedance only when both OE1 and OE2 are high; otherwise, data passes transparently from A to Y.

This device belongs to the SN54HC logic family and uses silicon-gate CMOS technology, delivering rail-to-rail output swing, input thresholds referenced to VCC (VIH = 70% VCC, VIL = 30% VCC), and robust noise immunity (typical VIH–VIL hysteresis >0.5 V at 4.5 V).

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	2 V to 6 V - supports direct interface with 3.3 V and 5 V logic domains without external level shifters.
Output Drive Current	±6 mA at 5 V - sufficient to drive 15 LSTTL loads or terminate unterminated transmission lines on backplanes.
Propagation Delay	Typical 10 ns at VCC = 4.5 V, CL = 50 pF - enables reliable operation in 50-MHz bus cycles with margin.
Quiescent Current	≤80 µA max ICC - minimizes standby power in battery-backed or thermally constrained military modules.
Operating Temperature	−55°C to +125°C - qualified for extended-range operation in airborne, space, and ground vehicle environments.
Input Leakage Current	≤1 µA max - ensures stable logic states even with high-impedance pull-ups in low-power wake-up circuits.
3-State Enable Timing	ten = 24 ns, tdis = 41 ns (VCC = 6 V, CL = 50 pF) - supports glitch-free bus arbitration and hot-swap sequencing.

Pinout & Package

8500101EA is supplied in a 16-pin Ceramic Dual In-line Package (CDIP-J), hermetically sealed with gold-plated leads and rated for military reliability per MIL-PRF-38535. The package features 0.3-inch body width, 0.1-inch lead pitch, and through-hole mounting compatible with legacy aerospace PCBs.

Pin/Terminal	Circuit Role	Design Meaning
1, 15	OE1, OE2	Dual active-low 3-state enable inputs - both must be low for output drivers to be active; either high forces Y into high-Z.
2, 4, 5, 7, 9, 12	A1–A6	Buffer input terminals - accept CMOS- or TTL-compatible logic signals; internally terminated to prevent floating.
3, 6, 8, 10, 13, 14	Y1–Y6	True (noninverting) buffered outputs - deliver rail-to-rail swing and support bus-wire-OR configurations.
11	VCC	Positive supply pin - requires local 0.1-µF ceramic decoupling adjacent to pin for noise suppression in EMI-prone environments.
16	GND	Ground reference - must be connected to system chassis ground via shortest possible path to minimize ground bounce.

Key Features

Feature	Design Value
Wide Supply Range (2–6 V)	Enables single-device compatibility across legacy 5 V and modern 3.3 V subsystems in mixed-voltage avionics racks.
Dual-Gated 3-State Control	Reduces bus contention risk by requiring coordinated OE1/OE2 assertion - critical for fault-tolerant multiprocessor interconnects.
High-Current Output Drivers	±6 mA drive at 5 V eliminates need for external bus transceivers in medium-length (≤15 cm) parallel address/data paths.
Low Input Current (≤1 µA)	Permits use with high-value pull-up resistors (>100 kΩ) in low-leakage sensor interface modules.
Military Temperature Range	Qualified from −55°C to +125°C per MIL-PRF-38535 - supports deployment in unheated UAV bays and engine-mounted controllers.

Equivalent & Alternatives

The following parts are listed as comparable options for similar hex noninverting buffer applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SNJ54HC365J	Identical electrical specs, same CDIP-J package, but marked per JANS specification with full QML Class V screening.	Required for programs mandating JANS-certified components; identical pinout and timing but higher test rigor and traceability.	Select SNJ54HC365J when JANS certification and lot-level conformance to MIL-PRF-19500 are contractually required.
SN54HC365J	Same die and package, but screened to Class B (not Class V); lower cost, no JANS marking, and reduced burn-in/test coverage.	Suitable for non-safety-critical subsystems where full QML-V is not mandated, e.g., payload telemetry interfaces.	Choose SN54HC365J for cost-sensitive military designs where full JANS qualification is unnecessary but −55°C to +125°C operation is essential.

Compared with 8500101EA, SNJ54HC365J offers identical performance with certified QML-V screening for mission-critical flight hardware, while SN54HC365J provides equivalent electrical behavior at lower cost for less stringent applications - all three share pinout, timing, and thermal specs.

FAQ

What is the exact package type and lead finish for 8500101EA?

8500101EA is packaged in a 16-pin Ceramic Dual In-line Package (CDIP-J) with gold-plated leads. It conforms to MIL-PRF-38535 Class V requirements and features hermetic sealing for moisture resistance in high-humidity operational environments. The package has 0.3-inch body width and 0.1-inch lead pitch, optimized for through-hole assembly on rigid military-grade PCBs.

Does 8500101EA support 3.3 V logic levels while powered from 5 V?

Yes, 8500101EA supports 3.3 V logic inputs when VCC = 5 V: its VIH threshold is 3.15 V (min) and VIL is 1.35 V (max) at 4.5 V supply, comfortably accommodating standard 3.3 V CMOS output swings. The device does not require level translation, making it suitable for mixed-voltage board designs where 3.3 V FPGAs drive 5 V peripherals via 8500101EA buffers.

How does the dual output-enable (OE1/OE2) architecture of 8500101EA improve system reliability?

The dual OE structure of 8500101EA requires both OE1 and OE2 to be low for outputs to be active - preventing accidental bus contention if one enable line fails high due to ESD or wiring fault. This redundancy reduces single-point failure risk in safety-critical avionics and engine control systems, where unintended 3-state release could corrupt memory or sensor data transfers.

Can 8500101EA drive a 50 Ω transmission line directly?

No, 8500101EA is not designed for direct 50 Ω line driving: its ±6 mA output drive at 5 V yields ~833 Ω effective source impedance (5 V / 6 mA), far above 50 Ω. It can drive unterminated stubs up to 15 cm or terminate 600 Ω+ buses, but for controlled-impedance traces, an external series resistor (e.g., 45 Ω) or dedicated line driver like SN65LVDS1 should be used alongside 8500101EA.

Is 8500101EA compliant with RoHS or green packaging standards?

No, 8500101EA is not RoHS-compliant: as a military CDIP-J device, it uses leaded solder and gold-plated leads per MIL-PRF-38535 requirements. It falls outside EU RoHS scope due to its exemption under Annex III for military and space applications. For commercial-grade RoHS alternatives, consider SN74HC365D (SOIC) or SN74HC365PWR (TSSOP), though these lack extended temperature and screening.
