74HCT08N,652

Overview

The NXP USA Inc. 74HCT08N,652 is a quad 2-input AND gate from the HCT logic family, housed in a 14-lead DIP plastic dual in-line package (SOT27-1). It operates within a supply voltage range of 4.5 V to 5.5 V and supports an ambient temperature range of -40 °C to +125 °C. The device complies with JEDEC standards JESD7A and JESD8-1A, featuring TTL-compatible input levels and ESD protection exceeding 2000 V (HBM) and 200 V (MM). Propagation delay is specified at 24 ns typ at 4.5 V with a 50 pF load.

Feature Summary

• Provides four independent 2-input AND logic functions
• Features TTL-compatible input levels for direct interfacing
• Includes input clamp diodes for high-voltage interface capability
• Offers robust electrostatic discharge protection

Applications

• Digital logic signal gating
• Data path selection
• Enable control circuits

Procurement Notes

Verify the specific ordering suffix '652' against current NXP documentation to confirm manufacturing origin and compliance status. Ensure the DIP14 package variant matches the required mechanical footprint. Confirm that the HCT logic level compatibility aligns with the system's existing TTL or CMOS voltage thresholds before finalizing procurement.

Selection Notes

Select this component when TTL-level inputs are required alongside CMOS performance characteristics. The HCT series ensures compatibility with standard TTL outputs while maintaining low power consumption. Verify that the operating voltage remains within the 4.5 V to 5.5 V range to guarantee correct logic threshold behavior and propagation delay specifications.

Part Context

This part belongs to the widely adopted 74HCT logic family, designed as a high-speed silicon-gate CMOS solution compatible with low-power Schottky TTL (LSTTL). The 74HCT08 specifically implements the fundamental AND function, serving as a building block for complex digital systems requiring reliable logical conjunction operations under standard industrial temperature conditions.

Replacement Considerations

Cross-reference with other manufacturers offering 74HCT08 DIP14 variants. Ensure equivalent pinout, logic functionality, and electrical characteristics such as input voltage thresholds and output drive strength match the original design requirements.
