DESCRIPTION

· The 74ALVC164245 is a high-performance, low-power, low-voltage, Si-gate CMOS device.
· It is a 16-bit dual supply translating transceiver with non-inverting 3-state bus compatible outputs.
· Designed to interface between 3 V and 5 V buses in mixed supply environments.
· Can be used as two 8-bit transceivers or one 16-bit transceiver.
· Direction control inputs (1DIR and 2DIR) determine data flow direction.
· Output enable inputs (1OE and 2OE) disable ports by placing them in high-impedance OFF-state.
· Pins nAn, nOE, and nDIR are referenced to VCC(A); pins nBn are referenced to VCC(B).
· In suspend mode, no current flows from the non-zero supply towards the zero supply.

FEATURES

· Wide supply voltage range: 1.5 V to 3.6 V for 3 V port (VCC(A)) and 1.5 V to 5.5 V for 5 V port (VCC(B)).
· CMOS low power consumption.
· Overvoltage tolerant inputs to 5.5 V.
· Direct interface with TTL levels.
· IOFF circuitry provides partial Power-down mode operation.
· Latch-up performance exceeds 100 mA per JESD 78 Class II Level B.
· Control inputs voltage range from 2.7 V to 5.5 V.
· High-impedance outputs when VCC(A) or VCC(B) = 0 V.
· Complies with JEDEC standards: JESD8-7, JESD8-5, and JESD8C.
· ESD protection: HBM exceeds 2000 V and CDM exceeds 1000 V.
· Specified from -40 °C to +85 °C and -40 °C to +125 °C.

APPLICATIONS
