74VHC244; 74VHCT244

Octal buffer/line driver; 3-state

Rev. 01 — 17 August 2009

Product data sheet

1. General description

The 74VHC244; 74VHCT244 are a high-speed Si-gate CMOS devices.

The 74VHC244; 74VHCT244 have octal non-inverting buffer/line drivers with 3-state

outputs. The 3-state outputs are controlled by the output enable inputs (nOE). A HIGH on

nOE causes the outputs to assume a high-impedance OFF-state.

2. Features

I Balanced propagation delays

I All inputs have a Schmitt-trigger action

I Inputs accepts voltages higher than V_CC

I Input levels:

N The 74VHC244 operates with CMOS input level

N The 74VHCT244 operates with TTL input level

I ESD protection:

N HBM JESD22-A114E exceeds 2000 V

N MM JESD22-A115-A exceeds 200 V

N CDM JESD22-C101C exceeds 1000 V

I Multiple package options

I Speciﬁed from −40 °C to +85 °C and from −40 °C to +125 °C
