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.

[1] All typical values are measured at VCC = 3.3 V (unless stated otherwise) and Tamb = 25 °C.
[2] The bus hold circuit is switched off when VI > VCC allowing 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 VI level.
[5] The specified overdrive current at the data input forces the data input to the opposite input state.

PD = CPD × VCC 2 × fi × N + Σ(CL × VCC 2 × fo) where:
fi = input frequency in MHz; fo = output frequency in MHz

VCC = supply voltage in Volts
N = number of inputs switching
Σ(CL × VCC 2 × fo) = sum of the outputs.
