Octal buffer/line driver; 3-state

Rev. 6 — 15 February 2021

Product data sheet

1. General description

The 74LVC244A-Q100; 74LVCH244A-Q100 is an octal non-inverting buffer/line driver with 3-state

outputs. The 3-state outputs are controlled by the output enable inputs 1OE and 2OE. A HIGH on

nOE causes the outputs to assume a high-impedance OFF-state. Schmitt-trigger action at all inputs

makes the circuit highly tolerant for slower input rise and fall times.

Inputs can be driven from either 3.3 V or 5.0 V devices. In 3-state operation, outputs can handle

5 V. These features allow the use of these devices as translators in a mixed 3.3 V and 5 V

environment.

The 74LVCH244A-Q100 bus hold on data inputs eliminates the need for external pull-up resistors

to hold unused inputs.

This product has been qualified to the Automotive Electronics Council (AEC) standard Q100

(Grade 1) and is suitable for use in automotive applications.

[2] The bus hold circuit is switched off when V_I> V_CCallowing 5.5 V on the input terminal.

[3] Valid for data inputs of bus hold parts only (74LVCH244A-Q100). Note that control inputs do not have a bus hold circuit.

[4] The specified sustaining current at the data input holds the input below the specified V_Ilevel.

[5] The specified overdrive current at the data input forces the data input to the opposite input state.
