description/ordering information

These octal buffers/drivers are designed

specifically for low-voltage (3.3-V) V

operation,

but with the capability to provide a TTL interface

to a 5-V system environment.

The ’LVTH540 devices are ideal for driving bus

lines or buffer-memory address registers. These

devices feature inputs and outputs on opposite

sides of the package that facilitate printed circuit

board layout.

SCBS681G − MARCH 1997 − REVISED OCTOBER 2003 description/ordering information (continued) The 3-state control gate is a 2-input AND gate with active-low inputs so that, if either output-enable (OE1 or OE2) input is high, all outputs are in the high-impedance state. Active bus-hold circuitry holds unused or undriven inputs at a valid logic state. Use of pullup or pulldown resistors with the bus-hold circuitry is not recommended.
