Overview
The SN74ALVCH16373DGG is a 16-bit transparent D-type latch featuring three-state outputs, manufactured by Texas Instruments. It operates within a supply voltage range of 1.65 V to 3.6 V and utilizes the ALVCH logic family. The device is housed in a 48-pin TSSOP package with a narrow body (0.240 inch width). Key electrical parameters include a propagation delay of 4.3 ns at 3.3 V and 3.6 ns at 2.5 V. It supports low-level output currents of 32 mA and high-level output currents of -24 mA, with a maximum static current of 40 uA.
Feature Summary
- Supports mixed-mode signal operations across 1.65 V to 3.6 V supplies
- Provides bus-hold circuitry on data inputs to eliminate external pull-up or pull-down resistors
- Features Ioff support for partial-power-down mode and back-drive protection
Applications
- High-density memory mapping
- Clock drivers
- Bus-oriented architectures
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm package type and tape-and-reel specifications. Ensure the component matches the required operating temperature range and voltage levels for your design. Cross-reference the manufacturer part number with authorized distributors to confirm authenticity and availability status before finalizing procurement plans.
Selection Notes
Select this component when designing systems requiring 16-bit latching with three-state outputs in low-voltage environments. The ALVCH series offers optimized performance for mixed-signal applications. Consider the 48-TSSOP package constraints and verify that the 32 mA drive capability meets the load requirements of the connected bus lines.
Part Context
This device belongs to the Texas Instruments SN74ALVCH16xxx series of 16-bit latches. It is designed for use in complex digital systems where data retention and bus isolation are critical. The ALVCH technology provides improved switching speeds and lower power consumption compared to standard CMOS technologies, making it suitable for portable and battery-operated devices.
Replacement Considerations
Check for direct replacements such as the SN74ALVCH16373DGGR or SN74ALVCH16373ADGVR. Verify pin compatibility and electrical characteristics before substitution.
