The 74LVC245A/74LVCH245A is a high-performance, low-power，low-voltage， Si-gate CMOS device, superior to most advanced CMOS compatible TTL families。Inputs can be driven from either 3.3V or 5V devices。In 3-State operation，outputs can handle 5V。These features allow the use of these devices as translators in a mixed 3.3V/5V environment。The 74LVC245A/74LVCH245A is an octal transceiver featuring non-inverting 3-State bus compatible outputs in both send and receive directions。 The ’245’ features an output enable (OE) input for easy cascading and a send/receive (DIR) input for direction control。OE controls the outputs so that the buses are effectively isolated。
