Nexperia USA Inc. 74AHC30PW,118

Overview

74AHC30PW,118 from Nexperia is an 8-input NAND gate in TSSOP14 package, designed for high-speed CMOS logic applications with balanced propagation delays, Schmitt-trigger inputs, and operation from 2.0 V to 5.5 V. It delivers 3.6 ns typical propagation delay at 5 V/15 pF and supports industrial temperature range (–40 °C to +125 °C), commonly used in address decoding, bus control, and system-level enable logic.

For engineers reviewing the 74AHC30PW,118 datasheet, 74AHC30PW,118 pinout, 74AHC30PW,118 application, or 74AHC30PW,118 equivalent, key selection criteria include input voltage compatibility (CMOS-level), output drive capability (±8 mA), thermal performance in TSSOP14, and functional equivalence to 74AHCT30PW for TTL-compatible designs.

Technical Context

This device implements a single 8-input NAND logic function with all inputs featuring Schmitt-trigger action for noise immunity and hysteresis. Its CMOS-level input thresholds scale with VCC (VIH = 0.7×VCC min, VIL = 0.3×VCC max), enabling robust interfacing across supply voltages from 2.0 V to 5.5 V.

It operates within JEDEC-standardized absolute maximum ratings (VCC up to +7.0 V, VI up to +7.0 V) and meets HBM ESD protection >2000 V and CDM >1000 V. The logic output drives ±8 mA while maintaining VOH ≥3.70 V and VOL ≤0.55 V over full temperature range.

FAQ

What is the maximum clock frequency supported by the 74AHC30PW,118?

The 74AHC30PW,118 is a combinational logic gate-not a clocked device-so it has no inherent clock frequency limit. Its usable toggle rate depends on propagation delay and load capacitance: at 5 V and 15 pF, 3.6 ns tpd supports signal transitions up to ~140 MHz in ideal conditions. System-level timing must account for input rise/fall times and board parasitics.

Can the 74AHC30PW,118 operate at 3.3 V with guaranteed performance?

Yes. The 74AHC30PW,118 is fully specified at VCC = 3.3 V ±0.3 V, with VIH ≥2.1 V, VIL ≤0.9 V, tpd ≤9.5 ns (CL = 15 pF), and output drive ≥4 mA. All static and dynamic parameters are guaranteed across –40 °C to +125 °C at this voltage.

Are the 'n.c.' pins on the TSSOP14 package required to be grounded or left floating?

All three 'n.c.' pins (9, 10, 13) are internally unconnected and must remain floating-no grounding, pulling, or routing is permitted. Connecting them may cause unpredictable behavior or increased leakage. The datasheet explicitly states they have no electrical or mechanical requirement for soldering.

How does the Schmitt-trigger input improve system reliability?

Schmitt-trigger inputs provide hysteresis (~0.3×VCC), raising the threshold for rising edges and lowering it for falling edges. This rejects noise transients <10 ns wide and eliminates chatter on slow-rising signals (e.g., from mechanical switches or long traces), preventing false logic transitions without external RC filtering.
