SN74LVC540APW Description

Short technical summary and product information.

The Texas Instruments SN74LVC540APW is an octal buffer/driver featuring inverting logic and 3-state outputs. Designed for high-speed applications, this component operates from a supply voltage range of 1.65V to 3.6V, making it suitable for mixed-voltage systems.

Key electrical characteristics include a maximum propagation delay of 5.3ns at 3.3V and output current capabilities of 24mA. The device supports mixed-mode signal operation on all ports, allowing 5V input/output voltage with a 3.3V VCC. Features like Ioff support live insertion, partial power down mode, and back drive protection enhance its utility in various designs.

Packaged in a 20-TSSOP, the SN74LVC540APW is designed for surface mounting. It operates within an ambient temperature range of -40°C to 125°C. The active low output enable pins (OE1 and OE2) control all eight channels, requiring both to be low for the outputs to be active. This part offers balanced outputs and very high speed performance, indicated by a tpd of 5-10ns.
