Description

General part information

SN74LVCH244A Series

The SN54LVCH244A octal buffer/line driver is designed for 2.7-V to 3.6-V VCCoperation, and the SN74LVCH244A octal buffer/line driver is designed for 1.65-V to 3.6-V VCCoperation.

These devices are organized as two 4-bit line drivers with separate output-enable (OE) inputs. WhenOEis low, these devices pass data from the A inputs to the Y outputs. WhenOEis high, the 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.
