PI74LPT16374AA

Shift Registers Overview

The PI74LPT16374AA is a 16-bit octal register featuring 16 D-type flip-flops with buffered common clock and 3-state outputs. It operates within a supply voltage range of 2.7V to 3.6V, supporting mixed-signal environments with 5V tolerant inputs and outputs. The device provides balanced output drive capabilities of 24 mA for both sourcing and sinking currents. It is housed in a 48-pin 240-mil wide plastic TSSOP package.

Shift Registers Feature Summary

• Supports 5V tolerant mixed signal mode operation allowing compatibility between 3V and 5V devices
• Features advanced low power CMOS design optimized for 3.3V applications
• Includes hysteresis on all inputs to improve noise immunity
• Provides ESD protection exceeding 2000V Human-Body Model standards

Shift Registers Applications

• Mixed 3.3V/5.0V system translation
• Bus drivers requiring high-output drive capability
• Memory address drivers
• System clock drivers

Shift Registers Procurement Notes

Verify the specific suffix 'AA' against manufacturer ordering codes, as datasheets list 'AE', 'VE', 'CAE', and 'CVE'. Confirm RoHS compliance status and lead times directly with Diodes Incorporated or authorized distributors, as this component may be obsolete or subject to change.

Shift Registers Selection Notes

Select this component when a 16-bit register with 3-state outputs is required for mixed-voltage logic interfaces. Ensure the application utilizes a 3.3V supply rail and requires 5V input tolerance. Verify that the 48-pin TSSOP package dimensions fit the PCB layout constraints.

Shift Registers Part Context

This part belongs to the LPT series of fast CMOS logic devices from Pericom Semiconductor, now part of Diodes Incorporated. It is functionally compatible with LCX and LVT families, offering pin-compatible upgrades for existing designs requiring improved drive strength and lower power consumption.

Shift Registers Replacement Considerations

Direct substitutes include PI74LPT16374AE, PI74LPT16374VE, PI74LPT16374CAE, and PI74LPT16374CVE. These variants share identical electrical characteristics but differ in packaging (TSSOP vs SSOP) and specific ordering suffixes.
