Nexperia USA Inc. 74AHC02PW-Q100J

Overview

74AHC02PW-Q100 from Nexperia is an automotive-qualified quad 2-input NOR gate in TSSOP14 package, operating from -40 °C to +125 °C with CMOS-level inputs, 5.5 V absolute max supply voltage, and propagation delay as low as 2.9 ns (VCC = 4.5–5.5 V, CL = 15 pF). It delivers balanced timing, Schmitt-trigger inputs, and input overvoltage tolerance-enabling robust logic interfacing in engine control units and ADAS sensor signal conditioning.

For engineers reviewing the 74AHC02PW-Q100 datasheet, 74AHC02PW-Q100 pinout, 74AHC02PW-Q100 application, or 74AHC02PW-Q100 equivalent, key selection criteria include AEC-Q100 Grade 1 qualification, TTL-compatible 74AHCT variant availability, TSSOP thermal performance, and verified NOR gate propagation delay vs. load capacitance across temperature extremes.

Technical Context

This device implements four independent 2-input NOR gates using high-speed Si-gate CMOS technology, fully compliant with JEDEC 7-A and pin-compatible with LSTTL. Its Schmitt-trigger inputs enable noise-immune signal reception, while input voltage tolerance beyond VCC supports mixed-voltage domain interfacing.

The logic function follows standard NOR truth table (L,L→H; X,H→L; H,X→L), with static output drive capability of ±8 mA at VCC = 4.5 V and dynamic power dissipation modeled via CPD = 7.0 pF. Propagation delays are characterized for both 15 pF and 50 pF loads across full automotive temperature range.

FAQ

Is 74AHC02PW-Q100 pin-compatible with standard 74-series NOR gates?

Yes - it is pin-compatible with Low-power Schottky TTL (LSTTL) devices such as 74LS02 and functionally compatible with 74HC02. The TSSOP14 footprint matches industry-standard 14-lead logic packages, enabling drop-in replacement in existing layouts without PCB revision.

What is the maximum clock frequency supported by this NOR gate?

This is a combinational logic device with no internal clock; its usable toggle rate depends on propagation delay and load. With 15 pF load and VCC = 5 V, tpd = 2.9 ns (typ), supporting reliable operation up to ~170 MHz in feedback configurations - confirmed by dynamic characterization in Table 7 of the datasheet.

Does this device require external pull-up or pull-down resistors on unused inputs?

No - all inputs feature Schmitt-trigger action and defined DC thresholds. Unused inputs must be tied to VCC or GND to prevent floating states; pull-up/pull-down resistors are unnecessary due to CMOS input structure and built-in hysteresis.

Can 74AHC02PW-Q100 interface directly with 3.3 V microcontrollers?

Yes - at VCC = 3.3 V, VIH = 2.1 V (min) and VIL = 0.9 V (max) align precisely with standard 3.3 V CMOS logic levels. Output VOH = 2.58 V (min) at IO = −4 mA ensures solid HIGH recognition by receiving 3.3 V inputs.
