TEXAS INSTRUMENTS 74HC373 D-Type Latch DIP20

The TEXAS INSTRUMENTS 74HC373 is an octal transparent D-Type Latch with 3-state outputs. This 8-bit latch is designed specifically for driving highly capacitive or relatively low-impedance loads. It is particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers.

While the latch-enable (LE) input is high, the Q outputs 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. An output-enable (OE) input places the eight outputs in either a normal logic state or a high-impedance state. In the high-impedance state, 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 interface or pull-up components. The OE input does not affect the internal operations of the latch, meaning old data can be retained or new data can be entered while the outputs are off.

Key Features

• High-current 3-state true outputs can drive up to 15 LSTTL loads
• Full parallel access for loading
