SN74ALVCH16373DGGR 16-bit transparent D-type latch
The SN74ALVCH16373DGGR is a high-performance, 16-bit transparent D-type latch from Texas Instruments, belonging to the advanced ALVCH (Advanced Low-Voltage CMOS) logic family, designed for high-speed data buffering and bus interface applications. This device operates from a 1.65V to 3.6V supply range, making it ideal for low-voltage, high-speed systems such as those based on modern microprocessors and digital signal processors. It features 16 latches with 3-state outputs, organized as two independent 8-bit sections, each controlled by a shared latch enable (LE) and a separate output enable (OE) input. Its primary function is to temporarily store (latch) data from a bus and provide a high-drive, low-noise interface, making it essential for isolating data buses, holding address information, and driving heavily loaded backplanes.
This 16-bit latch supports live insertion and removal (hot-swap) with power-up 3-state and BIAS VCC pins, which precharge the I/O ports to a known state to prevent bus contention. It boasts a high-speed operation with a maximum propagation delay of approximately 3 ns at 3.3V, supporting fast data throughput. The outputs can source or sink up to 24 mA, providing strong drive capability for bus lines. All inputs and outputs are tolerant to voltages up to 3.6V, allowing for mixed-voltage communication.
SN74ALVCH16373DGGR 16-bit latch Applications
● Microprocessor and DSP System Buses: Serves as an address or data latch for interfacing with memory (SRAM, DRAM) and peripherals, providing temporary storage and buffering.
● Data Communication and Networking Equipment: Used in routers, switches, and line cards for buffering data packets and control signals across high-speed backplanes.
● Industrial Control and Automation: Acts as an interface buffer between central controllers and I/O modules, sensor arrays, or actuator banks in PLCs and distributed control systems.
● Test and Measurement Instrumentation: Provides signal buffering and data capture for digital channels in logic analyzers, protocol testers, and automated test equipment.
● High-Speed Data Acquisition Systems: Latches parallel data from ADCs or other data sources before processing or transmission to a host system.
