Nexperia USA Inc. 74AHC00BQ,115

Overview

74AHC00BQ,115 from Nexperia is a quad 2-input NAND gate IC in DHVQFN14 package, operating from 2.0 V to 5.5 V supply, featuring overvoltage-tolerant inputs (up to 5.5 V), Schmitt-trigger inputs, and guaranteed operation from −40 °C to +125 °C. It serves as a level-translating logic gate in mixed-voltage digital systems such as industrial I/O interfaces and microcontroller peripheral buffering.

For engineers reviewing the 74AHC00BQ,115 datasheet, 74AHC00BQ,115 pinout, 74AHC00BQ,115 application, or 74AHC00BQ,115 equivalent, key selection criteria include input voltage tolerance, propagation delay at 3.3 V/5 V, thermal performance in compact PCB layouts, and compatibility with 1.8 V–5 V logic domain interfacing.

Technical Context

This device implements four independent CMOS NAND gates with rail-to-rail output swing, input hysteresis via integrated Schmitt triggers, and overvoltage-tolerant inputs enabling safe interfacing between 1.8 V, 3.3 V, and 5 V logic domains without external level shifters. All inputs tolerate up to 5.5 V regardless of VCC setting.

Designed for high-noise industrial environments, it delivers balanced tPLH/tPHL propagation delays (≤7.0 ns at VCC = 5.0 V, CL = 15 pF), low ICC (≤40 μA at VCC = 5.5 V), and robust ESD protection (HBM >2000 V, CDM >1000 V), meeting JEDEC JS-001/JS-002 standards.

FAQ

Can 74AHC00BQ,115 operate with a 1.8 V supply?

No. The absolute minimum supply voltage is 2.0 V per the recommended operating conditions table. At 1.8 V, VIH and VOH specifications fall outside guaranteed limits, risking incorrect logic interpretation and reduced noise margin. Use 74LVC00 for true 1.8 V operation.

Is the exposed thermal pad on the DHVQFN14 package required to be soldered?

No. Per datasheet note, the thermal pad has no electrical or mechanical requirement to be soldered. If soldered, it must remain floating or connect to GND-never to VCC or signal nets-to avoid parasitic coupling or thermal stress.

Does 74AHC00BQ,115 support hot-swap insertion into a live 5 V bus?

Yes-its overvoltage-tolerant inputs (rated to 5.5 V) allow safe connection to an active 5 V bus before VCC is applied, provided VCC remains at 0 V until system power sequencing completes. Output drivers remain in high-impedance state until VCC stabilizes.

How does propagation delay vary between 3.3 V and 5.0 V supply?

At CL = 15 pF, tpd is ≤7.9 ns at VCC = 3.3 V and ≤5.5 ns at VCC = 5.0 V. This 2.4 ns improvement reflects faster internal transistor switching at higher VCC, enabling tighter timing margins in 5 V systems without increasing power consumption disproportionately.
