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
n Balanced propagation delays
n All inputs have a Schmitt-trigger action
n Inputs accepts voltages higher than V
CC
n Input levels:
u The 74VHC244 operates with CMOS input level
u The 74VHCT244 operates with TTL input level
n ESD protection:
u HBM JESD22-A114E exceeds 2000 V
u MM JESD22-A115-A exceeds 200 V
u CDM JESD22-C101C exceeds 1000 V
n Multiple package options
n Specified from −40 °C to +85 °C and from −40 °C to +125 °C
