SN54LV573 and SN74LV573 are octal transparent D-type latches designed for 2.7V to 5.5V VCC operation. These devices feature 3-state outputs designed specifically for driving highly capacitive or relatively low-impedance loads. They are particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers.
The SN54LV573 and SN74LV573 are octal transparent D‑type latch devices with three‑state outputs, suitable for buffer registers, I/O ports, bidirectional bus drivers, and working registers. They feature latch‑enable and output‑enable inputs that allow data to be latched or placed in a high‑impedance state, enabling flexible bus interfacing without additional pull‑up components.
The devices operate over a wide voltage range (2.7 V to 5.5 V), support military temperature specifications (‑55 °C to 125 °C for SN54LV573, ‑40 °C to 85 °C for SN74LV573), and include ESD protection exceeding 2000 V. Detailed electrical characteristics, timing requirements, and package power dissipation limits are provided, along with a standard warranty notice.
