74LVC244A; 74LVCH244A

Octal buffer/line driver; 3-state

Rev. 8 — 26 June 2013

Product data sheet

1. General description

The 74LVC244A; 74LVCH244A 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 bus hold on data inputs eliminates the need for external pull-up

resistors to hold unused inputs.

2. Features and benefits

 5 V tolerant inputs/outputs for interfacing with 5 V logic

 Wide supply voltage range from 1.2 V to 3.6 V

 CMOS low-power consumption

 Direct interface with TTL levels

 Inputs accept voltages up to 5.5 V

 High-impedance when V_CC= 0 V

 Bus hold on all data inputs (74LVCH244A only)

 Complies with JEDEC standard:

 JESD8-7A (1.65 V to 1.95 V)

 JESD8-5A (2.3 V to 2.7 V)

 JESD8-C/JESD36 (2.7 V to 3.6 V)

 ESD protection:

 HBM JESD22-A114F exceeds 2000 V

 MM JESD22-A115B exceeds 200 V

 CDM JESD22-C101E exceeds 1000 V

 Specified from 40 C to +85 C and 40 C to +125 C
