74LVC244A - Octal buffer/line driver

Datasheet Summary

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.

Features

  • 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 VCC = 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.

74LVC244A; 74LVCH244A Octal buffer/line driver; 3-state Rev. 11 — 29 April 2021 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.
