74HC245; 74HCT245

Octal bus transceiver; 3-state

The 74HC245; 74HCT245 is an 8-bit transceiver with 3-state outputs. The device features an output enable (OE) and send/receive (DIR) for direction control. A HIGH on OE causes the outputs to assume a high-impedance OFF-state. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.

特性

  • Wide supply voltage range from 2.0 to 6.0 V

  • CMOS low power dissipation

  • High noise immunity

  • Octal bidirectional bus interface

  • Non-inverting 3-state outputs

  • Input levels:

    • For 74HC245: CMOS level

    • For 74HCT245: TTL level

  • Complies with JEDEC standards

    • JESD8C (2.7 V to 3.6 V)

    • JESD7A (2.0 V to 6.0 V)

  • Latch-up performance exceeds 100 mA per JESD 78 Class II Level B

  • ESD protection:

    • HBM JESD22-A114F exceeds 2000 V

    • MM JESD22-A115-A exceeds 200 V

  • Multiple package options

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