The SN74AHCT573 from Texas Instruments is an octal transparent D-type latch designed for digital logic applications. This device features 3-state outputs, allowing them to be placed in a high-impedance state, which is beneficial for bus-oriented systems. The latch-enable (LE) input controls whether the Q outputs follow the D inputs or retain their current state.
Key electrical characteristics include a maximum clock frequency of 110 MHz, TTL-compatible CMOS input levels, and a wide operating temperature range from -40°C to 125°C. The outputs provide a maximum sink current (IOL) of 8 mA and a maximum source current (IOH) of -8 mA. ESD protection is rated up to 2000V for the Human-Body Model.
This latch is available in various surface mount and through-hole packages, including PDIP, SOIC, TSSOP, and others. The flow-through pinout and balanced outputs are designed for ease of use in circuit design. Latch-up performance exceeds 250 mA per JESD 17, ensuring robust operation.
The SN74AHCT573 is suitable for applications requiring data storage and buffering in digital systems, memory interfaces, and control logic.
