Nexperia USA Inc. 74HCT30PW-Q100J

Overview

74HCT30PW-Q100 from Nexperia is an automotive-grade 8-input NAND gate in TSSOP14 package, operating from 4.5 V to 5.5 V supply, with TTL-compatible inputs, propagation delay of 16–42 ns (VCC = 4.5 V), and qualified per AEC-Q100 Grade 1 (−40 °C to +125 °C) for engine control and body electronics.

For engineers reviewing the 74HCT30PW-Q100 datasheet, 74HCT30PW-Q100 pinout, 74HCT30PW-Q100 application, or 74HCT30PW-Q100 equivalent, this page delivers verified functional behavior, automotive thermal and ESD specs, input/output voltage thresholds, dynamic timing under load, and precise pin mapping for PCB layout and logic-level interface validation.

Technical Context

This device implements a single 8-input negative-AND logic function with CMOS output stage and TTL-level input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V). It features integrated input clamp diodes enabling safe interfacing to voltages exceeding VCC when used with current-limiting resistors.

Designed for automotive environments, it supports full rail-to-rail output swing (VOH ≥ 3.98 V at IO = −4.0 mA; VOL ≤ 0.26 V at IO = 4.0 mA), exhibits low static ICC (≤ 40 μA at VCC = 5.5 V), and maintains stable operation across −40 °C to +125 °C ambient with no derating up to 81 °C.

FAQ

What is the maximum input voltage the 74HCT30PW-Q100 can tolerate when VCC = 5.0 V?

The absolute maximum input voltage is VCC + 0.5 V = 5.5 V, but with clamp diodes enabled, inputs may safely accept up to 7 V when series current-limiting resistors limit IIK to ±20 mA. Exceeding 7 V risks permanent damage even with resistors, per Table 4 limiting values.

Can unused inputs (Pins 9, 10, 13) be left floating in a production design?

No - all unused inputs must be tied to VCC or GND. Floating CMOS inputs cause increased ICC, unpredictable logic states, and potential oscillation due to noise coupling. Pins 9, 10, and 13 are explicitly marked "n.c." and contain no internal connection, but adjacent inputs (A–H) must never float.

Does the 74HCT30PW-Q100 support mixed-voltage operation, such as 3.3 V inputs with 5 V VCC?

No - the 74HCT30PW-Q100 is TTL-input compatible only at VCC = 4.5–5.5 V. Its VIH minimum is 2.0 V, but input thresholds are referenced to VCC; applying 3.3 V inputs while VCC = 5 V is acceptable, but 3.3 V inputs with VCC < 4.5 V violates recommended operating conditions and may cause marginal switching.

How does the TSSOP14 package affect thermal performance compared to SO14?

The SOT402-1 (TSSOP14) package has lower thermal resistance: Ptot derates linearly at 7.3 mW/K above 81 °C, whereas SO14 (SOT108-1) derates at 10.1 mW/K above 100 °C. Thus, at 125 °C ambient, TSSOP14 allows ~10 % higher continuous power before derating limits are reached, assuming identical PCB copper area.
