NXP Semiconductors 74AHC30PW,112

Overview

74AHC30PW,112 from Nexperia is an 8-input NAND gate in TSSOP14 package, designed for high-speed CMOS logic interfacing with balanced propagation delays (3.6 ns typical at 5 V, 15 pF), Schmitt-trigger inputs enabling noise immunity, and operation across -40 °C to +125 °C. It supports mixed-voltage systems with input tolerance up to 7.0 V and drives standard CMOS loads in industrial control sequencers and programmable logic glue circuits.

For engineers reviewing the 74AHC30PW,112 datasheet, 74AHC30PW,112 pinout, 74AHC30PW,112 application, or 74AHC30PW,112 equivalent, key selection criteria include propagation delay vs. load capacitance, input voltage level compatibility (CMOS), thermal derating behavior in TSSOP14, and pin-compatible alternatives for board-level redesigns requiring identical 8-input NAND functionality.

Technical Context

This device implements a single 8-input NAND function using high-speed Si-gate CMOS technology compliant with JEDEC Std 7-A and pin-compatible with LSTTL. All eight inputs feature Schmitt-trigger action, enabling robust noise rejection on slow or noisy signal lines without external hysteresis components.

It operates over a wide supply range (2.0 V to 5.5 V) with CMOS-level input thresholds (VIH = 3.85 V min at VCC = 5.5 V), low static current (ICC ≤ 40 μA at 5.5 V), and output drive capability of ±8 mA at 4.5 V - sufficient to directly interface with multiple downstream CMOS gates or LED indicators.

FAQ

What is the maximum operating frequency supported by the 74AHC30PW,112?

The 74AHC30PW,112 does not specify a maximum clock frequency, as it is a combinational logic device. Its usable toggle rate depends on propagation delay and load capacitance: at 5 V and 15 pF, tpd = 3.6 ns (typ), supporting reliable operation up to ~140 MHz in feedback-free configurations. System-level timing must account for worst-case 12.0 ns delay at 125 °C and 50 pF load.

Can the 74AHC30PW,112 accept 5 V inputs while powered from a 3.3 V supply?

Yes - all inputs tolerate voltages up to 7.0 V regardless of VCC, per Absolute Maximum Ratings. At VCC = 3.3 V, VIH = 2.1 V (min), so a 5 V input is safely recognized as HIGH and causes no damage or latch-up, making it ideal for level translation in mixed-supply systems without external resistors or buffers.

Are the n.c. pins (9, 10, 13) required to be grounded or left floating?

Pins 9, 10, and 13 are internally not connected and may be left unconnected. Nexperia documentation states they may be tied to GND for mechanical stability or solder mask definition, but no electrical requirement exists. Floating is electrically safe and commonly used in space-constrained layouts.

How does thermal derating apply to the TSSOP14 package of the 74AHC30PW,112?

The TSSOP14 package (SOT402-1) has a total power dissipation limit of 500 mW at Tamb ≤ 81 °C. Above 81 °C, Ptot derates linearly at 7.3 mW/K - e.g., at 100 °C, max allowable power drops to 366 mW. This reflects junction-to-air thermal resistance and must be verified against actual board layout and airflow conditions.
