SN74AVC16373ZQLR

Overview

The SN74AVC16373ZQLR is a 16-bit transparent D-type latch with 3-state outputs manufactured by Texas Instruments. It operates within a voltage range of 1.2V to 3.6V and utilizes Microstar Junior BGA-56 packaging. Key electrical parameters include propagation delays of 5.8ns, 6.8ns, 5.7ns, 3.3ns, and 2.8ns at nominal voltages. Maximum output currents are rated at -12mA (IOH) and 12mA (IOL). The device supports an operating temperature range from -40°C to 85°C and features a maximum supply current of 0.04mA.

Feature Summary

• Provides 16-bit data latching capability with non-inverting logic polarity.
• Incorporates 3-state outputs for effective bus driving and isolation.
• Supports low-voltage operation suitable for mixed-signal systems.

Applications

• High-density digital signal processing interfaces
• Memory buffer applications in portable electronics
• System control logic in embedded controllers

Procurement Notes

Verify the specific suffix ZQLR against the official datasheet to confirm the Microstar Junior package type and tape-and-reel configuration. Ensure compatibility with the target PCB footprint and reflow soldering profile requirements. Cross-reference the manufacturer's latest documentation for any updates regarding lead-free compliance or RoHS status prior to final procurement decisions.

Selection Notes

Select this component when a 16-bit latch with 3-state outputs is required in a compact BGA form factor. It is suitable for designs needing low power consumption and operation across a wide voltage range from 1.2V to 3.6V. Consider the propagation delay specifications relative to system clock speeds and ensure the thermal characteristics meet the application's environmental constraints.

Part Context

This part belongs to the SN74AVC16373 family of 16-bit transparent D-type latches. The family offers various package options including TSSOP and TVSOP, but the ZQLR suffix specifically denotes the Microstar Junior BGA-56 variant. This series is designed for high-speed data transfer applications requiring low voltage operation and minimal power dissipation.

Replacement Considerations

Direct substitutes within the same family include SN74AVC16373DGGR and SN74AVC16373DGG, though these utilize different packages such as TSSOP-48. Verify pinout compatibility and package dimensions before substitution. Other series like SN74LVC16373 or SN74AHCT16373 differ in voltage ranges and technology families and require careful evaluation.
