description
The SN54LVCH244A octal buffer/line driver is designed for 2.7-V to 3.6-V V
CC
operation and the
SN74LVCH244A octal buffer/line driver is designed for 1.65-V to 3.6-V V
CC
operation.
These devices are organized as two 4-bit line drivers with separate output-enable (OE) inputs. When OE is low,
these devices pass data from the A inputs to the Y outputs. When OE is high, the outputs are in the
high-impedance state.
Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.
Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of these devices as translators
in a mixed 3.3-V/5-V system environment.
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 SN54LVCH244A is characterized for operation over the full military temperature range of –55
°
C to 125
°
C.
The SN74LVCH244A is characterized for operation from –40
°
C to 85
°
C.
