What are the key features of 74ALVTH16373GRE4?
- 16-bit transparent D-type latch with active-low output enable, providing simultaneous data capture and tri-state bus isolation in a single 48-pin TSSOP package
- ALVTH logic family supports 2.5 V and 3.3 V supply operation with 5 V tolerant inputs, simplifying mixed-voltage bus interfacing between legacy and modern logic devices
- 24 mA sink current per output with 30 pF load capacitance rating enables fast switching on heavily loaded PCB data buses in high-speed FPGA and memory controller applications
What is 74ALVTH16373GRE4 used for?
The 74ALVTH16373GRE4 is used in high-speed data bus buffering and address latching applications between FPGAs, CPUs, and memory arrays in embedded computing and network switch designs. Its 16-bit width and tri-state output capability enable efficient address/data multiplexing on shared backplane buses operating at 2.5 V or 3.3 V supply rails. The active-low output enable makes it well suited for decoded chip-select glue logic and demultiplexing address buses in microprocessor systems requiring sub-nanosecond propagation delays.

Frequently Asked Questions
What supply voltage range does 74ALVTH16373GRE4 support and can its inputs be driven from a 5 V source?
74ALVTH16373GRE4 operates from a 2.5 V or 3.3 V supply voltage and features 5 V tolerant inputs. This allows the device to interface directly between legacy 5 V logic devices and modern 2.5 V or 3.3 V FPGA I/O banks without level-shifting circuitry, simplifying board design in mixed-voltage digital systems.
How many bits does 74ALVTH16373GRE4 latch and what is its output drive current?
74ALVTH16373GRE4 latches 16 bits simultaneously in transparent mode and holds them when the latch-enable signal is de-asserted. Each output drives up to 24 mA sink current at 0.55 V output voltage, sufficient to drive 30 pF bus capacitance and multiple parallel logic inputs on a PCB data bus without external buffering.
What is the role of the active-low output enable on 74ALVTH16373GRE4 in a multiplexed bus design?
The active-low output enable (OE) on 74ALVTH16373GRE4 tri-states all 16 outputs when de-asserted, disconnecting the latch from the output bus. This allows multiple 74ALVTH16373GRE4 devices to share a single 16-bit bus with only one device driving at a time, implementing bank-selected address or data multiplexing in multi-master embedded processor and FPGA memory controller designs.
Which package does 74ALVTH16373GRE4 use and how does it compare to through-hole 16-bit latch alternatives?
74ALVTH16373GRE4 is housed in a 48-pin TSSOP (R-PDSO-G48) SMT package with 0.5 mm pin pitch, significantly smaller than a DIP-48 through-hole alternative. The TSSOP footprint reduces PCB area by approximately 60% versus DIP, enabling denser bus logic layouts in compact industrial controllers, network switches, and SBC designs while maintaining the same 16-bit latch functionality.
