74LV244  
Octal buffer/line driver; 3-state  
Rev. 5 — 24 September 2021  
Product data sheet  
1. General description  
The 74LV244 is an 8-bit buffer/line driver with 3-state outputs. The device can be used as two 4-bit  
buffers or one 8-bit buffer. The device features two output enables (1OE and 2OE), each controlling  
four of the 3-state outputs. A HIGH on nOE causes the outputs to assume a high-impedance  
OFF-state. Inputs include clamp diodes. This enables the use of current limiting resistors to  
interface inputs to voltages in excess VCC  
.
2. Features and benefits  
Wide supply voltage range from 1.0 to 5.5 V  
CMOS low power dissipation  
Latch-up performance exceeds 100 mA per JESD 78 Class II Level B  
Optimized for low voltage applications: 1.0 V to 3.6 V  
Accepts TTL input levels between VCC = 2.7 V and VCC = 3.6 V  
Typical VOLP (output ground bounce) < 0.8 V at VCC = 3.3 V; Tamb = 25 °C  
Typical VOHV (output VOH undershoot) > 2 V at VCC = 3.3 V; Tamb = 25 °C  
Complies with JEDEC standards:  
JESD8-7 (1.65 V to 1.95 V)  
JESD8-5 (2.3 V to 2.7 V)  
JESD8C (2.7 V to 3.6 V)  
JESD36 (4.5 V to 5.5 V)  
ESD protection:  
HBM JESD22-A114F exceeds 2000 V  
MM JESD22-A115-A exceeds 200 V  
Specified from -40 °C to +85 °C and from -40 °C to +125 °C
