The SNJ54ALS373J is a high-performance, octal transparent D-type latch designed by Texas Instruments. This integrated circuit is part of the advanced low-power Schottky (ALS) family, which is renowned for its exceptional speed and energy efficiency. The product is especially suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers in a wide range of digital systems.

Key Features

• Logic Family: ALS - Advanced Low-Power Schottky
• Latch Type: Transparent D-Type
• Number of Latches: 8 (Octal)
• Output Type: 3-State Outputs
• Package: J-Lead Ceramic Package
• Operating Temperature Range: -55°C to 125°C
• Supply Voltage: 4.5V to 5.5V

The device features a set of eight latches with 3-state outputs for bus-organized systems. The transparent nature of the latches means that while the enable (LE) input is high, the Q outputs will follow the data (D) inputs. When LE is taken low, the Q outputs are latched at the levels that were set up at the D inputs.

A buffered output-control (OC) input can be used to place the eight outputs in either a normal logic state (high or low logic levels) or the high-impedance state. In the latter mode, the outputs neither load nor drive the bus lines significantly. The high-impedance state and increased drive provide the capability to drive bus lines without the need for interface or pull-up components.

The SNJ54ALS373J is encapsulated in a durable ceramic package that ensures reliable operation even under extreme environmental conditions. This makes it an excellent choice for military and aerospace applications, as well as other high-reliability environments.

Applications

• Buffer Registers
• I/O Ports
