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 VCC 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
