Nexperia USA Inc. 74HC366D-Q100,118

Overview

74HC366D-Q100 from Nexperia is an AEC-Q100 Grade 1 qualified hex inverting buffer/line driver with 3-state outputs, operating from 2.0 V to 6.0 V supply, delivering 7.8 mA sink/source drive at 4.5 V, with propagation delay as low as 12 ns (VCC = 4.5 V, Tamb = 25 °C), and used in automotive body control modules for bidirectional bus isolation and signal conditioning.

For engineers reviewing the 74HC366D-Q100 datasheet, 74HC366D-Q100 pinout, 74HC366D-Q100 application, or 74HC366D-Q100 equivalent, key selection criteria include its CMOS-level input compatibility, -40 °C to +125 °C automotive temperature range, dual active-low output enable control, high-impedance state leakage < ±0.5 μA, and SO16 package thermal derating profile.

Technical Context

This device implements six independent inverting buffers, each with separate input (nA) and output (nY) terminals, where output state is controlled by two shared active-low enable inputs (OE1, OE2). All outputs enter high-impedance OFF-state when either OE1 or OE2 is HIGH.

Input clamp diodes allow safe interfacing to voltages exceeding VCC when used with current-limiting resistors. Static characteristics are specified across three temperature grades (-40 °C to +125 °C), and dynamic timing includes enable/disable times (ten ≤ 38 ns, tdis ≤ 38 ns at VCC = 4.5 V, Tamb = -40 °C to +125 °C) and transition time (tt ≤ 15 ns).

Key Specifications

Pinout & Package

FAQ

Can 74HC366D-Q100 operate reliably at 125 °C junction temperature?

Yes - it is fully characterized and guaranteed over -40 °C to +125 °C ambient, with static parameters (VOH, VOL, II, IOZ) and dynamic timing (tpd, ten, tdis) validated at maximum temperature. Thermal derating begins at 110 °C for SO16 package (12.4 mW/K), requiring appropriate PCB copper area and airflow in sealed enclosures.

What is the maximum capacitive load each output can drive while maintaining timing specs?

Each output is specified for CL = 50 pF in dynamic tests, with tpd ≤ 26 ns and tt ≤ 15 ns at VCC = 4.5 V and Tamb = -40 °C to +125 °C. Driving >50 pF increases propagation delay linearly and may violate setup/hold margins; for >100 pF loads, add series termination or use a dedicated line driver.

How do OE1 and OE2 interact when both are asserted?

Both OE1 and OE2 are active-low and ORed internally: if either is LOW, outputs are enabled; only when both are HIGH do all six outputs enter high-impedance state. This allows flexible control - e.g., OE1 for primary enable and OE2 for fault-induced shutdown - without external logic.

Does this device support hot-swap insertion into a live backplane?

Yes - input clamp diodes and controlled output transition behavior (tt ≤ 15 ns) prevent destructive current surges during insertion. However, ensure OE1/OE2 are held HIGH (outputs disabled) until VCC stabilizes and system bias is established, per Nexperia's recommended power-up sequence in section 6 of the datasheet.
