SN74AHCT1G32DCK3

Overview

The SN74AHCT1G32DCK3 is a single-channel, two-input positive-OR gate from the Texas Instruments 74AHCT logic family. It operates within a supply voltage range of 4.5 V to 5.5 V and features CMOS technology with TTL-compatible inputs. The device provides one output line driven by two input lines in an SC-70-5 surface-mount package. Key electrical characteristics include a low-level output current of 8 mA and a high-level output current of -8 mA. Propagation delay is specified at 7.9 ns under standard conditions. The component supports industrial operating temperatures ranging from -40°C to +125°C.

Feature Summary

• Single-channel OR logic function with two inputs and one output
• TTL-compatible input thresholds for direct interfacing with TTL devices
• High noise immunity and low power consumption typical of CMOS technology
• Industrial temperature rating suitable for demanding environments

Applications

• Signal routing and selection in digital control systems
• Logic combination in data processing circuits
• Interface modules between TTL and CMOS subsystems
• General-purpose logic functions in embedded hardware

Procurement Notes

Verify the specific suffix DCK3 against official Texas Instruments documentation to confirm pinout and package dimensions. Ensure compatibility with 5V logic levels due to the AHCT series specifications. Confirm RoHS compliance status through the manufacturer's latest datasheet or environmental information page before integration into regulated products.

Selection Notes

Select this component when TTL-compatible inputs are required alongside CMOS performance benefits. The AHCT series bridges the gap between older TTL standards and modern low-voltage CMOS processes. Consider the SC-70-5 package size for space-constrained designs requiring single-gate functionality without additional complexity.
