DESCRIPTION

· The 74LVC4245A is an octal dual supply translating transceiver with 3-state bus compatible outputs.

· It interfaces between 3 V and 5 V buses in mixed supply environments.

· Features include an output enable input (OE) and a send/receive input (DIR) for direction control.

· High impedance OFF-state when OE is HIGH, isolating buses.

· No current path between supplies in suspend mode when either supply is zero.

· Schmitt-trigger action at all inputs for tolerance to slower input rise and fall times.

FEATURES

· 5 V tolerant inputs/outputs for 5 V logic interfacing.

· Wide supply voltage range: 1.5 V to 3.6 V for 3 V bus, 1.5 V to 5.5 V for 5 V bus.

· CMOS low-power consumption.

· TTL interface capability at 3.3 V.

· Overvoltage tolerant control inputs up to 5.5 V.

· High-impedance when VCC(A) = 0 V.

· Complies with JEDEC standards JESD8B/JESD36.

· Latch-up performance meets JESD78 Class 1 requirements.

· ESD protection: HBM exceeds 2000 V, CDM exceeds 1000 V.

· Multiple package options.

· Specified from -40 °C to +125 °C.

APPLICATIONS

· Mixed 3 V and 5 V supply environments.

· Bus translation in multi-voltage systems.

· Systems requiring high-impedance state isolation.

· Applications needing overvoltage tolerance and ESD protection.

· Low-power consumption designs.

· Industrial temperature range applications.
