74LV244 Octal buffer/line driver 3-state Rev. 4 1 March 2016 Product data sheet 1. General description The 74LV244 is a low-voltage Si-gate CMOS device and is pin and function compatible with 74HC244 and 74HCT244. The 74LV244 is an octal non-inverting buffer/line driver with 3-state outputs. The output enable inputs 1OE and 2OE control the 3-state outputs. A HIGH on nOE causes the outputs to assume a high impedance OFF-state. The 74LV244 is identical to the 74LV240 but has non-inverting outputs. 2. Features and benefits Wide operating voltage: 1.0 V to 5.5 V Optimized for low voltage applications: 1.0 V to 3.6 V Accepts TTL input levels between V = 2.7 V and V = 3.6 V CC CC Typical V (output ground bounce) < 0.8 V at V = 3.3 V T = 25 C OLP CC amb Typical V (output V undershoot) > 2 V at V = 3.3 V T = 25 C OHV OH CC amb Complies with JEDEC standard no. 7A Multiple package options ESD protection: HBM JESD22-A114F exceeds 2000 V MM JESD22-A115-A exceeds 200 V 3.
