Nexperia USA Inc. 74HCT10D-Q100J

Overview

74HCT10D-Q100 from Nexperia is an automotive-grade triple 3-input NAND gate in SO14 (SOT108-1) package, operating from -40 °C to +125 °C with TTL-compatible inputs, 4.5–5.5 V supply range, and propagation delay of 14–36 ns at VCC = 4.5 V - used for combinatorial logic control in engine management and body electronics.

For engineers reviewing the 74HCT10D-Q100 datasheet, 74HCT10D-Q100 pinout, 74HCT10D-Q100 application, or 74HCT10D-Q100 equivalent, this page delivers verified functional behavior, AEC-Q100 Grade 1 qualification status, input/output voltage thresholds, dynamic timing under CL = 50 pF, and direct pin-to-function mapping per SOT108-1 layout.

Technical Context

This device implements three independent 3-input NAND gates with CMOS output stages and TTL-level input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V), enabling direct interfacing with legacy 5 V TTL logic families without level translation. Each gate exhibits rail-to-rail output swing and supports fan-out of ≥10 LS-TTL loads.

Input clamp diodes allow safe operation with input voltages exceeding VCC when current-limited, and ESD protection meets HBM >2000 V and CDM >1000 V per JS-001/JS-002. The logic function follows standard NAND truth table: output LOW only when all three inputs are HIGH.

FAQ

What is the maximum allowable input voltage beyond VCC for 74HCT10D-Q100?

The device includes input clamp diodes that permit safe operation with input voltages up to VCC + 0.5 V, provided external current-limiting resistors restrict IIK to ±20 mA per pin. Exceeding this voltage without limiting risks permanent damage per Absolute Maximum Ratings.

Can 74HCT10D-Q100 drive a 50 pF capacitive load at 10 MHz?

Yes - with tpd = 14–36 ns and tt = 7–22 ns at CL = 50 pF and VCC = 4.5 V, the device maintains clean edges and timing margins well below 100 ns period, supporting reliable operation at 10 MHz toggle rate in combinatorial paths.

Is there a difference in propagation delay between 74HC10D-Q100 and 74HCT10D-Q100?

Yes: at VCC = 4.5 V and CL = 50 pF, 74HC10D-Q100 has tpd = 11–29 ns, while 74HCT10D-Q100 is slower at 14–36 ns due to optimized input stage for TTL compatibility - a deliberate trade-off for interoperability, not performance loss.

Does 74HCT10D-Q100 require external pull-up or pull-down resistors on unused inputs?

No - unused inputs must be terminated to VCC or GND to prevent floating states and increased ICC, but no external resistors are needed beyond direct connection; internal input structure does not require biasing, and floating inputs cause undefined logic and elevated power consumption.
