74ALVC164245DGG:11 Datasheet PDF - NXP

The 74ALVC164245DGG:11 is a 16-bit dual supply Translating Transceiver featuring non-inverting 3-state bus compatible outputs in both send and receive directions. It is designed to interface between a 3 and 5V bus in a mixed 3 and 5V supply environment. The 74ALVC164245 is a high-performance low-power low-voltage Si-gate CMOS device superior to most advanced CMOS compatible TTL families. This device can be used as two 8-bit transceivers or one 16-bit transceiver. The direction control inputs determine the direction of the data flow. nDIR enables data from nAn ports to nBn ports. nDIR enables data from nBn ports to nAn ports. The output enable inputs, when HIGH, disable both nAn and nBn ports by placing them in a high-impedance OFF-state. Pins nAn, nOE and nDIR are referenced to VCC(A) and pins nBn are referenced to VCC(B). In suspend mode, when one of the supply voltages is zero, there will be no current flow from the non-zero supply towards the zero supply.
