74AHCT1G32GZYL

Overview

The Nexperia 74AHCT1G32GZYL is a single-channel, 2-input OR gate integrated circuit manufactured in the 74AHCT logic series. It operates within a supply voltage range of 4.5V to 5.5V and features TTL-compatible input levels. The device provides symmetrical output impedance with high noise immunity and low power dissipation. It is housed in a compact 5-XSON (1.1x0.85mm) surface-mount package. Key electrical parameters include a maximum propagation delay of 8.8ns at 5V with 50pF load, static current consumption of 1µA, and output drive capabilities of 8mA for both high and low states across an operating temperature range of -40°C to +125°C.

Feature Summary

• TTL-compatible input levels ensure direct interfacing with standard TTL logic devices without requiring level shifting components.
• Overvoltage tolerant inputs allow safe operation in mixed-voltage environments by accepting signals up to 5.5V while powered at lower voltages.
• High noise immunity and balanced propagation delays contribute to reliable signal integrity in high-speed digital applications.

Applications

• Signal routing and selection in mixed-voltage digital systems
• Logic function implementation in portable consumer electronics
• Interface circuits between TTL and CMOS logic domains

Procurement Notes

Verify the exact suffix GZYL corresponds to the 5-XSON package variant rather than the standard TSSOP version. Confirm RoHS3 compliance and REACH status through official Nexperia documentation prior to integration. Ensure ESD handling protocols are followed during assembly due to the small form factor and sensitivity of CMOS inputs.

Selection Notes

Select this component when a single OR gate is required in space-constrained designs utilizing the 5-XSON footprint. Choose this part over standard TSSOP versions if board real estate is limited. Verify that the 4.5V minimum supply voltage aligns with the system power rails, as it does not support lower voltage operation like the AHC series.

Part Context

This component belongs to the Nexperia 74AHCT family, which combines the speed of AHC technology with TTL-compatible inputs. The '1G' designation indicates a single-gate configuration, while '32' identifies the OR logic function. The GZYL suffix specifically denotes the 5-XSON package type, distinguishing it from other packaging options like TSSOP or SC-70-5 available in the same logical family.

FAQ

What is the maximum input voltage tolerance for the 74AHCT1G32GZYL?

The inputs are overvoltage tolerant up to 5.5V, allowing them to interface with 5V logic even if the device is powered at lower voltages within its specified range.

Does the 74AHCT1G32GZYL support operation below 4.5V?

No, the AHCT series requires a supply voltage between 4.5V and 5.5V to maintain TTL-compatible input thresholds. Lower voltages may result in undefined logic states.
