74AHC244; 74AHCT244  
Octal buffer/line driver; 3-state  
Rev. 05 — 20 December 2007  
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  
Balanced propagation delays  
All inputs have a Schmitt-trigger action  
Inputs accepts voltages higher than VCC  
For 74AHC244 only: operates with CMOS input levels  
For 74AHCT244 only: operates with TTL input levels  
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
