1. General description
The 74ABT245 is an 8-bit transceiver with 3-state outputs. The device features an output enable (OE) and send/receive (DIR) for direction control. A HIGH on OE causes the outputs to assume a high-impedance OFF-state. This device is fully specified for partial power down applications using IOFF. The IOFF circuitry disables the output, preventing the potentially damaging backflow current through the device when it is powered down.
2. Features and benefits
Octal bidirectional bus interface 3-State buffers Supply voltage range from 4.5 to 5.5 V BiCMOS high speed and output drive Direct interface with TTL levels Output capability: +64 mA/–32 mA Power-up 3-State Live insertion/extraction permitted Inputs are disabled during 3-state mode IOFF circuitry provides partial Power-down mode operation Latch-up protection exceeds 500 mA per JESD78 class II level A ESD protection:
HBM JESD22-A114F exceeds 2000 V MM JESD22-A115-A exceeds 200 V Specified from -40 °C to +85 °C
