74VHCT14BQ,115

Inverter Gates Overview

The Nexperia 74VHCT14BQ,115 is a hex inverting Schmitt trigger implemented in high-speed Si-gate CMOS technology. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an ambient temperature range from -40 °C to +125 °C. The device provides balanced propagation delays with a maximum of 9.0 ns at 4.5 V to 5.5 V with a 15 pF load. It features TTL input levels and includes ESD protection exceeding 2000 V (HBM) and 1000 V (CDM). The component is housed in a DHVQFN14 package (SOT762-1) measuring 2.5 mm by 3 mm.

Inverter Gates Feature Summary

• Hex inverting buffers with Schmitt-trigger action for jitter-free output signals
• TTL-compatible input levels for direct interfacing with low-power Schottky TTL logic
• ESD protection compliant with ANSI/ESDA/JEDEC standards

Inverter Gates Applications

• Wave and pulse shapers
• Astable multivibrators
• Monostable multivibrators

Inverter Gates Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm the DHVQFN14 package type and thermal enhancement specifications. Ensure that the selected variant aligns with the required operating temperature range and voltage constraints for the target application environment.

Inverter Gates Selection Notes

Select this component when TTL-level inputs are required alongside Schmitt-trigger noise immunity in a compact surface-mount form factor. The VHCT series ensures compatibility with LSTTL systems while offering higher speed performance compared to standard HC or HCT families. Verify power dissipation limits relative to the PCB thermal design.

Inverter Gates Part Context

This part belongs to the 74VHC/VHCT family of high-speed Si-gate CMOS devices. These components are pin-compatible with Low-power Schottky TTL (LSTTL) and comply with JEDEC standard No. 7A. The family offers multiple package options including SO14, TSSOP14, and DHVQFN14 to accommodate various board space and thermal requirements.

Inverter Gates Replacement Considerations

Direct functional replacements include other 74VHCT14 variants in different packages such as 74VHCT14D (SO14) or 74VHCT14PW (TSSOP14), provided the physical footprint allows for adaptation.
