74VHC244; 74VHCT244

Octal buffer_line driver; 3-state

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.

Features and benefits

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