74AHC594T16-13

Overview

The 74AHC594T16-13 is an advanced high-speed CMOS device manufactured by Diodes Incorporated, packaged in a TSSOP-16 surface-mount configuration. It functions as an 8-bit shift register with an 8-bit output register. The component operates within a supply voltage range of 2.0V to 5.5V and features Schmitt trigger inputs that accept up to 5.5V. It provides push-pull outputs capable of sinking or sourcing 8mA at VCC = 4.5V. The device includes independent active-low reset functions for both the shift and storage registers.

Feature Summary

• Features separate shift and storage registers with independent clocking capabilities
• Includes dedicated serial data output pin (Q7S) for cascading multiple devices
• Provides independent active-low reset controls for shift and storage registers

Applications

• Serial to parallel data conversion
• Computer peripherals
• Appliances
• Industrial control systems

Procurement Notes

Verify the specific package code T16 corresponds to the TSSOP-16 footprint required for your PCB layout. Confirm the -13 suffix indicates the standard 2500-unit tape and reel packaging format. Ensure input pins are tied to VCC or ground when unused to prevent floating states. Check RoHS compliance documentation if environmental regulations apply to your manufacturing process.

Selection Notes

Select this component when a high-speed CMOS logic solution is required for serial-to-parallel expansion. The wide operating voltage range supports various digital logic families. The inclusion of a serial output facilitates daisy-chaining multiple units to expand I/O capacity without consuming additional microcontroller pins. Verify that the TSSOP-16 package dimensions fit your available board space.

Part Context

This part belongs to the 74AHC series of advanced high-speed CMOS logic integrated circuits produced by Diodes Incorporated. The 74AHC594 variant specifically implements an 8-bit shift register architecture. The T16-13 designation identifies the physical TSSOP-16 package style and the associated tape and reel packaging quantity.

Replacement Considerations

Compatible substitutes include the 74AHC594S16-13, which utilizes an SO-16 package instead of TSSOP-16. Other generic equivalents may exist but require verification of pinout compatibility and electrical characteristics against the official datasheet specifications.
