Nexperia USA Inc. 74HCT00D-Q100,118

Overview

74HCT00D-Q100 from Nexperia is an automotive-qualified quad 2-input NAND gate in SO14 (SOT108-1) package, operating from -40 °C to +125 °C with TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V), 4.5–5.5 V supply range, and propagation delay of 12–29 ns (CL = 50 pF). It serves as a fundamental logic building block in automotive body control modules for signal inversion and enable/disable gating.

For engineers reviewing the 74HCT00D-Q100 datasheet, 74HCT00D-Q100 pinout, 74HCT00D-Q100 application, or 74HCT00D-Q100 equivalent, key selection criteria include AEC-Q100 Grade 1 qualification, TTL-level input compatibility, SO14 package mechanical footprint, guaranteed operation up to +125 °C ambient, and dynamic performance under 50 pF load.

Technical Context

This device implements four independent 2-input NAND gates using silicon-gate CMOS technology with TTL-compatible input circuitry-ensuring direct interfacing with legacy 5 V TTL outputs without level shifting. Each gate features input clamp diodes enabling safe interface to voltages exceeding VCC when used with current-limiting resistors.

It complies with JEDEC standards JESD8C (2.7–3.6 V) and JESD7A (2.0–6.0 V), supports latch-up immunity >100 mA per JESD78 Class II Level B, and delivers high noise immunity via hysteresis-free but robust VIH/VIL margins across temperature and supply voltage.

FAQ

Is 74HCT00D-Q100 pin-compatible with standard 74LS00?

Yes - it uses identical SO14 pinout (SOT108-1) and matches the 74LS00's logic function and input/output voltage thresholds. Its TTL-compatible inputs accept LS-family outputs directly, and its outputs drive LS loads with full fan-out margin (IOH = -4.0 mA, IOL = 4.0 mA at VCC = 4.5 V).

Can 74HCT00D-Q100 operate at 3.3 V supply?

No - the 74HCT00D-Q100 is specified only for 4.5–5.5 V operation per its recommended conditions. At 3.3 V, input thresholds fall outside TTL specification (VIH minimum becomes undefined), risking unreliable switching; use 74HC00D-Q100 instead for 2.0–6.0 V wide-range CMOS operation.

What is the maximum capacitive load this device can drive reliably?

It is characterized up to 50 pF (per dynamic test condition), with typical transition times of 6–19 ns. Driving >50 pF increases propagation delay nonlinearly and may cause output ringing; for heavier loads, add series termination or buffer stages to maintain signal integrity and timing margins.

Does the SO14 package include exposed thermal pad?

No - the SOT108-1 (SO14) package has no thermal pad. Thermal dissipation relies on copper traces connected to pins 7 (GND) and 14 (VCC); for high-duty-cycle applications, use thermal vias under these pins and maximize copper area to meet Ptot = 500 mW limit at +125 °C ambient.
