SN74AHC16373 16-Bit Transparent D-Type Latches with 3-State Outputs

The SN74AHC16373 from Texas Instruments is a high-performance, 16-bit transparent D-type latch designed for the latch-up and storage of binary information. This integrated circuit features 3-state outputs that enable direct connection to a bus-oriented system. Fabricated with advanced silicon-gate CMOS technology, it provides the user with a robust latch that is both high-speed and low-power.

Each of the 16-bit latches is D-type, transparent, and has a separate latch-enable (LE) and output-enable (OE) control. When LE is high, the flip-flops appear transparent to the data, and when LE is taken low, the data that meets the setup time is latched. Data appears on the bus when the OE is low. When OE is high, the outputs are in a high-impedance state, which means they neither load the bus nor drive it, allowing for bus line control in a shared-bus setup.

The SN74AHC16373 operates at a voltage range of 4.5 V to 5.5 V, making it compatible with typical 5V systems. It supports a wide operating temperature range, ensuring reliable performance in varying environmental conditions. The device's inputs are designed to tolerate voltages up to 5.5V, even when the device is in the off-state, which adds a layer of protection against unexpected voltage spikes.

Key features of this product include:

• 16-bit wide transparent D-type latches with 3-state outputs
• Operating voltage range of 4.5 V to 5.5 V
• Control inputs tolerate up to 5.5 V
• Low power consumption for energy-efficient designs
• High-impedance state during power-up and power-down
• Supports live insertion and withdrawal (partial-power-down mode)
• Industry-standard footprint for easy integration

Applications for the SN74AHC16373 are diverse, ranging from temporary data storage in computing systems to interfacing and bus-driving where high-speed, low-power operation is crucial. Its robust design ensures that it is suitable for demanding applications such as industrial control systems, telecommunications, and consumer electronics.

Overall, the SN74AHC16373 from Texas Instruments is a reliable and versatile component that provides an optimal solution for data-latching requirements in a wide array of electronic systems.
