SN74LV244A
- V CC operation of 2 V to 5.5 V
- Maximum t pd of 6.5 ns at 5 V
- Typical V OLP (output ground bounce) <0.8 V at V CC = 3.3 V, T A = 25°C
- Typical V OHV (output V OH undershoot) >2.3 V at V CC = 3.3 V, T A = 25°C
- Support mixed-mode voltage operation on all ports
- I off supports partial-power-down mode operation
- Latch-up performance exceeds 250-mA per JESD 17
The SN74LV244A octal buffers and line drivers are designed for 2-V to 5.5-V V CC operation.
The SN74LV244A devices are designed specifically to improve both performance and density of the 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. These devices are organized as two 4-bit line drivers with separate output-enable ( OE) inputs.
