74LVC4245A

Octal dual supply translating transceiver; 3-state

The 74LVC4245A is an octal dual supply translating transceiver featuring 3-state bus compatible outputs in both send and receive directions. It is designed to interface between a 3 V and 5 V bus in a mixed 3 V and 5 V supply environment. The device features an output enable input (OE) and a send/receive input (DIR) for direction control. A HIGH on OE causes the outputs to assume a high-impedance OFF-state, effectively isolating the buses. In suspend mode, when either supply is zero, there is no current path between supplies. VCCA ≥ VCCB, except in suspend mode. Schmitt-trigger action at all inputs makes the circuit tolerant of slower input rise and fall times.

Features and benefits

  • 5 V tolerant inputs/outputs, for interfacing with 5 V logic

  • Wide supply voltage range:

    • 3 V bus (VCC(B)): 1.5 V to 3.6 V

    • 5 V bus (VCC(A)): 1.5 V to 5.5 V

  • CMOS low-power consumption

  • TTL interface capability at 3.3 V

  • Overvoltage tolerant control inputs to 5.5 V

  • High-impedance when VCC(A) = 0 V

  • Complies with JEDEC standard no. JESD8B/JESD36

  • Latch-up performance meets requirements of JESD78 Class 1

  • ESD protection:

    • HBM: ANSI/ESDA/JEDEC JS-001 class 2 exceeds 2000 V

    • CDM: ANSI/ESDA/JEDEC JS-002 class C3 exceeds 1000 V

  • Multiple package options

  • Specified from -40 °C to +85 °C and -40 °C to +125 °C
