Octal bus transceiver; 3-state
General descriptionThe 74ALVC245 is an octal transceiver featuring non-inverting 3-state bus compatible
outputs in both send and receive directions. The 74ALVC245 features an output enable
input (OE) for easy cascading and send/receive input (DIR) for direction control. OE
controls the outputs, so that the buses are effectively isolated.
Features Wide supply voltage range from 1.65 V to 3.6 V Complies with JEDEC standard: JESD8-7 (1.65 V to 1.95 V) JESD8-5 (2.3 V to 2.5 V) JESD8B/JESD36 (2.7 V to 3.6 V) 3.6 V tolerant inputs/outputs CMOS low-power consumption Direct interface with TTL levels (2.7 V to 3.6 V) Power-down mode Latch-up performance exceeds 250 mA ESD protection: HBM JESD22-A114E exceeds 2000V MM JESD22-A115-A exceeds 200V
