Texas Instruments SN74LS373 Octal D-type Transparent Latches with 3-state Outputs SN74LS373NSR

The SN74LS373 Octal D-type Transparent Latch features eight latches with 3-state outputs, designed for driving capacitive loads and interfacing with bus systems without additional components. The device allows full parallel access for loading and includes buffered control inputs for improved noise rejection. The latches operate in a transparent mode when the enable input is high, allowing the Q outputs to follow the D inputs. When the enable input is low, the outputs retain the last data state. The high-impedance state can be activated via a buffered output-control input, ensuring minimal loading on the bus lines. This product is suitable for applications such as buffer registers, I/O ports, and bidirectional bus drivers. The SN74LS373 is available in various package options, including the NS package.
