Product Overview: 74ACT16373DL from Texas Instruments

The 74ACT16373DL is a high-speed, 16-bit D-type transparent latch with 3-state outputs designed by Texas Instruments. This integrated circuit (IC) is part of the 74ACT series, which is renowned for its advanced high-speed CMOS (Complementary Metal-Oxide Semiconductor) technology. The device is optimized for use in systems that require the capture and retention of multiple data lines simultaneously.

Constructed with two sets of eight latches with individual latch-enable (LE) inputs, the 74ACT16373DL enables users to control the flow of data by toggling the LE inputs. When the latch-enable input is high, the Q outputs follow the data (D) inputs. Conversely, when the latch-enable input is low, the Q outputs are preserved at the levels set up at the D inputs prior to the transition of the LE from high to low.

The 74ACT16373DL features 3-state outputs, which include a disabled state. This allows for connection to a bus or multiple outputs without the risk of conflict. The 3-state control (OE) inputs are used to place the eight outputs in either a normal logic state (high or low) or the high-impedance state. In the high-impedance state, the outputs neither load the bus nor interfere with the operation of other drivers.

The device operates over a wide voltage range of 4.5V to 5.5V, making it compatible with TTL (Transistor-Transistor Logic) levels, and it can drive up to 24mA at the output, ensuring good current drive capability. The input and output interface levels are TTL-compatible, allowing for easy interfacing with other TTL logic devices.

Encased in a 48-pin plastic SSOP (Shrink Small Outline Package), the 74ACT16373DL is designed for space-conscious applications requiring high-density circuitry. Its reliability and performance make it suitable for a wide range of applications, including memory address latching, data multiplexing, and various temporary storage tasks in computer, communication, and data processing systems.

With its combination of high speed, low power consumption, and robust latch capabilities, the Texas Instruments 74ACT16373DL is an excellent choice for designers looking to enhance the performance of their digital systems.
