Nexperia USA Inc. 74AHC30BQ,115

Overview

74AHC30BQ,115 from Nexperia is an 8-input NAND gate in a DHVQFN14 (SOT762-1) package, operating over -40 °C to +125 °C. It features CMOS-level inputs, balanced propagation delays (max 8.0 ns at VCC = 5.0 V, CL = 50 pF), Schmitt-trigger inputs for noise immunity, and input voltage tolerance up to 7.0 V - enabling robust interfacing in mixed-voltage logic systems such as industrial control sequencers and FPGA I/O expansion.

For engineers reviewing the 74AHC30BQ,115 datasheet, 74AHC30BQ,115 pinout, 74AHC30BQ,115 application, or 74AHC30BQ,115 equivalent, this device serves as a high-speed, low-power combinational logic element with verified thermal-enhanced QFN packaging, TTL-compatible variants (74AHCT30BQ), and JEDEC-compliant absolute maximum ratings - critical for board-level timing integrity and signal fan-in consolidation.

Technical Context

The 74AHC30BQ implements a single 8-input NAND function using high-speed Si-gate CMOS technology, fully compliant with JEDEC Std. 7-A and pin-compatible with LSTTL. Its Schmitt-trigger inputs provide hysteresis (typ. 0.3 V at VCC = 5 V), rejecting fast transient noise on slow-rising signals - essential in noisy industrial bus environments.

All eight inputs accept voltages up to 7.0 V independent of VCC, supporting level-shifting without external circuitry. The output drives ±25 mA with VOH ≥ 3.70 V and VOL ≤ 0.55 V under full load (IO = ±8.0 mA), ensuring reliable interfacing with downstream CMOS and TTL loads across its full temperature range.

FAQ

Can the 74AHC30BQ,115 operate with a 3.3 V supply and interface directly with 5 V microcontroller GPIOs?

Yes. Its inputs tolerate up to +7.0 V independent of VCC, so 5 V GPIO outputs can drive it safely at VCC = 3.3 V. Output VOH will be ~3.3 V, sufficient for CMOS loads but marginal for TTL; verify receiver VIH thresholds. No level shifter is needed for input-side interfacing.

Is the exposed thermal pad (Pin 1) required to be soldered to ground?

No. Per Nexperia documentation, the thermal pad is electrically isolated and has no internal connection. It may remain unsoldered or be floated; if soldered, it must connect only to GND or remain unconnected - never to VCC or signal nets - to avoid parasitic coupling or thermal stress.

What is the maximum clock frequency at which the 74AHC30BQ,115 can reliably gate a signal?

It is not a clocked device and has no internal clock. As a combinational NAND gate, its usable edge rate is governed by propagation delay (≤8.0 ns) and input transition rate (≤20 ns/V). For clean gating of periodic signals, input edges should exceed 125 MHz (8 ns period) only if system timing margins accommodate worst-case tpd + skew.

Are the 'n.c.' pins (9, 10, 13) safe to route over or place vias near?

Yes. Pins 9, 10, and 13 are confirmed not connected internally - no bond wires, no silicon routing. PCB layout may route traces or place non-critical vias adjacent to them without electrical impact. Avoid placing high-speed or high-current nets directly under the pad due to potential solder wicking during reflow.
