Overview
Description
The 74FCT540T octal buffer/line driver is similar in function to the FCT240T, except that the inputs and outputs are on opposite sides of the package. This pinout arrangement makes these devices especially useful as output ports for microprocessors and as backplane drivers, allowing ease of layout and greater board density. The 74FCT540T operates at -40C to +85C
Features
- A and C speeds
- Low input and output leakage ?1 uA (max.)
- CMOS power levels
- True TTL input and output compatibility
- VOH = 3.3V (typ.)
- VOL = 0.3V (typ.)
- High Drive outputs (-15mA IOH, 64mA IOL)
- Meets or exceeds JEDEC standard 18 specifications
- Power off disable outputs permit "live insertion"
- Available in 20 pin SOIC and QSOP packages
