SN74LVC573ADGVR Octal Transparent D-Type Latches by Texas Instruments

The SN74LVC573ADGVR from Texas Instruments is a high-performance, octal transparent D-type latch with 3-state outputs designed for 2-V to 3.6-V V_CC operation. This integrated circuit is part of the LVC family, which is known for its low-voltage operation and high-speed interface technology. It is particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers in a wide range of digital applications.

With its 8-bit data storage capability, the device allows data on the D inputs to be stored in the latches on a low-to-high transition of the clock (CLK) input. The latch enable (LE) input can be used to isolate the D inputs from the outputs, providing a controlled data flow path. Once LE is high, the Q outputs will follow the D inputs. When LE is low, the Q outputs will hold the last data presented before the transition of LE.

The SN74LVC573ADGVR features 3-state outputs, which can be put in a high-impedance state, effectively disconnecting the output from the circuit. This is particularly useful for sharing a common data bus and for reducing power consumption by disconnecting unused circuitry.

Manufactured in Texas Instruments' advanced CMOS technology, the SN74LVC573ADGVR ensures reduced power consumption without sacrificing speed. It also provides a balanced propagation delay and transition times, which is crucial for maintaining signal integrity in high-speed data pathways. The device is characterized for operation from -40°C to 85°C, making it reliable in a variety of environmental conditions.

The compact design is encapsulated in a 16-pin TSSOP (DGVR) package, which is ideal for space-constrained applications. Its small form factor combined with the power and speed of the LVC family makes the SN74LVC573ADGVR an excellent choice for designers looking to optimize their high-speed digital designs.
