Product Overview: 74AC16373DLR by Texas Instruments

The 74AC16373DLR is a high-performance, 16-bit D-type transparent latch with 3-state outputs, designed and manufactured by the reputable Texas Instruments (TI). This integrated circuit is part of TI's Advanced CMOS Logic (AC) family, which is renowned for its robustness and high-speed operation. The device is specifically engineered to meet the demands of high-speed memory buffering and data storage applications.

This product features two separate 8-bit latches with individual latch-enable (LE) and output-enable (OE) controls for each section. This allows for flexible control of the input and output data, making the 74AC16373DLR highly versatile for a wide range of uses. The transparent latches mean that when LE is high, the Q outputs follow the data (D) inputs. As soon as LE is taken low, the Q outputs are latched at the levels that were set up at the D inputs.

Another key feature of the 74AC16373DLR is its 3-state outputs, which can be set to either a high, low, or high-impedance state. The high-impedance state is crucial for shared data lines where multiple devices may need to take turns driving the line without interference. By utilizing the OE control, the outputs can be placed in this high-impedance state, ensuring safe and efficient data sharing on common buses.

The device is fabricated with advanced silicon-gate CMOS technology. This technology provides the 74AC16373DLR with its high-speed operation while maintaining the low power dissipation of CMOS circuitry. The latch is designed to operate from a 2V to 6V VCC supply voltage, making it suitable for interfacing with both TTL and CMOS logic levels and adaptable to various system voltages.

For ease of integration into your systems, the 74AC16373DLR is offered in a 48-pin SSOP (Shrink Small Outline Package) that is characterized for operation from -40°C to 85°C. This temperature range ensures reliable performance in a variety of environmental conditions.

Overall, the 74AC16373DLR from Texas Instruments is a reliable and efficient solution for designers looking to implement high-speed latching mechanisms in their digital systems. Its dual-latch design, combined with the flexibility of 3-state outputs, makes it an excellent choice for applications requiring quick and precise control over data flow.
