74AHCT259PW-Q100J

Latches Overview

The 74AHCT259PW-Q100J is an 8-bit addressable latch manufactured by NXP USA Inc. in a TSSOP16 package (SOT403-1). It operates within a supply voltage range of 4.5 V to 5.5 V and supports ambient temperatures from -40 °C to +125 °C. The device features TTL input levels, balanced propagation delays, and Schmitt-trigger actions on all inputs. It includes active LOW common reset (MR) and latch enable (LE) controls.

Latches Feature Summary

• Combines demultiplexer and 8-bit latch functionality with serial-to-parallel capability
• Inputs accept voltages higher than VCC for robust signal interfacing
• Provides random addressable data entry with output available from each storage bit
• Qualified to AEC-Q100 Grade 1 standards for automotive applications

Latches Applications

• General purpose digital system storage
• Active HIGH 8-channel decoding or demultiplexing
• Addressable latch mode for single-line data writing

Latches Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and temperature range. Ensure compatibility with the target application's voltage requirements before procurement. Confirm that the component meets the necessary automotive qualification standards if used in vehicle systems.

Latches Selection Notes

Select this component when an 8-bit addressable latch with TTL-compatible inputs is required. It is suitable for designs needing high-speed Si-gate CMOS performance with balanced propagation delays. Consider the TSSOP16 package constraints and ensure the operating environment falls within the specified temperature limits.

Latches Part Context

This part belongs to the 74AHC/AHCT259-Q100 family of high-speed Si-gate CMOS devices. It is pin compatible with Low-power Schottky TTL (LSTTL) and complies with JEDEC standard No. 7-A. The product is designed for general-purpose storage applications in digital systems.

Latches Replacement Considerations
