description
The ’LV540A devices are octal buffers/drivers
designed for 2-V to 5.5-V V
CC
operation.
These devices are ideal for driving bus lines or
buffer memory address registers. They feature
inputs and outputs on opposite sides of the
package to facilitate printed circuit board layout.
The 3-state control gate is a two-input AND gate
with active-low inputs so that if either
output-enable (OE1 or OE2) input is high, all
corresponding outputs are in the high-impedance
state. The outputs provide inverted data when
they are not in the high-impedance state.
To ensure the high-impedance state during power up or power down, OE should be tied to V
CC
through a pullup
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
The SN54LV540A is characterized for operation over the full military temperature range of –55
°
C to 125
°
C.
The SN74LV540A is characterized for operation from –40
°
C to 85
