SN74AHCT14DGVR

Overview

The SN74AHCT14DGVR is a hex inverter integrated circuit manufactured by Texas Instruments, belonging to the 74AHCT logic family. It features six independent Schmitt-trigger inverters housed in a 14-pin TVSOP package. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum propagation delay of 8 ns at 5 V with a 50 pF load. It provides symmetric output drive currents of 8 mA for both high and low states. The component is rated for operation across an extended temperature range from -40°C to +85°C.

Feature Summary

• Integrates six independent Schmitt-trigger inverters for noise-immune signal conditioning
• Ensures TTL-compatible input thresholds through the AHCT logic architecture
• Delivers symmetrical 8 mA output drive capability for robust load handling
• Provides controlled propagation delays suitable for high-speed digital applications

Applications

• Signal conditioning for noisy digital environments requiring hysteresis
• Waveform shaping and pulse generation circuits
• TTL-to-CMOS level translation interfaces
• Clock buffer and driver stages in digital systems

Procurement Notes

Verify the specific suffix DGVR corresponds to the TVSOP-14 package and reel packaging configuration. Confirm RoHS compliance status and manufacturing origin details against the latest datasheet revision. Ensure the operating voltage requirements align strictly with the 4.5 V to 5.5 V specification range to prevent device malfunction or damage during integration.

Selection Notes

Select this component when TTL-compatible inputs are required alongside CMOS output characteristics. The Schmitt-trigger functionality is essential for applications involving slow-rise-time signals or high-noise environments. Verify that the 14-pin TVSOP package fits the available PCB footprint and thermal constraints. Consider the 8 ns propagation delay limit when designing timing-critical paths.

Part Context

This part belongs to the SN74AHCT series, which bridges TTL and CMOS technologies. Unlike standard AHC variants, the AHCT series accepts TTL logic levels directly. The SN74AHC14 serves as the non-TTL counterpart with CMOS-compatible inputs. The DGVR suffix indicates surface-mount packaging optimized for automated assembly processes in consumer and industrial electronics.

FAQ

What is the input threshold compatibility of the SN74AHCT14DGVR?

The device features TTL-compatible input thresholds, allowing it to interface directly with TTL logic outputs without additional level shifting components.

How does the Schmitt trigger feature benefit this inverter?

The Schmitt trigger inputs provide hysteresis, which filters out noise and prevents multiple switching events caused by slow-rising or oscillating input signals.

What is the maximum operating supply voltage for this IC?

The maximum recommended supply voltage is 5.5 V. Operation beyond this limit may compromise device integrity or performance specifications.
