Product data sheet
1. General description
The 74AHC244; 74AHCT244 is a high-speed Si-gate CMOS device.
The 74AHC244; 74AHCT244 has 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
s Balanced propagation delays
s All inputs have a Schmitt-trigger action
s Inputs accepts voltages higher than VCC
s For 74AHC244 only: operates with CMOS input levels
s For 74AHCT244 only: operates with TTL input levels
s ESD protection:
x HBM JESD22-A114E exceeds 2000 V
x MM JESD22-A115-A exceeds 200 V
x CDM JESD22-C101C exceeds 1000 V
s Multiple package options
s Specified from 40 °C to +85 °C and from 40 °C to +125 °C
