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 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
