74LVC244A; 74LVCH244A  
Octal buffer/line driver; 3-state  
Rev. 8 — 26 June 2013  
Product data sheet  
1. General description  
The 74LVC244A; 74LVCH244A is an octal non-inverting buffer/line driver with 3-state  
outputs. The 3-state outputs are controlled by the output enable inputs 1OE and 2OE.  
A HIGH on nOE causes the outputs to assume a high-impedance OFF-state.  
Schmitt-trigger action at all inputs makes the circuit highly tolerant for slower input rise  
and fall times.  
Inputs can be driven from either 3.3 V or 5.0 V devices. In 3-state operation, outputs can  
handle 5 V. These features allow the use of these devices as translators in a mixed  
3.3 V and 5 V environment.  
The 74LVCH244A bus hold on data inputs eliminates the need for external pull-up  
resistors to hold unused inputs.  
2. Features and benefits  
5 V tolerant inputs/outputs for interfacing with 5 V logic  
Wide supply voltage range from 1.2 V to 3.6 V  
CMOS low-power consumption  
Direct interface with TTL levels  
Inputs accept voltages up to 5.5 V  
High-impedance when VCC = 0 V  
Bus hold on all data inputs (74LVCH244A only)  
Complies with JEDEC standard:  
JESD8-7A (1.65 V to 1.95 V)  
JESD8-5A (2.3 V to 2.7 V)  
JESD8-C/JESD36 (2.7 V to 3.6 V)  
ESD protection:  
HBM JESD22-A114F exceeds 2000 V  
MM JESD22-A115B exceeds 200 V  
CDM JESD22-C101E exceeds 1000 V  
Specified from 40 C to +85 C and 40 C to +125 C
