74HC541; 74HCT541

Octal buffer/line driver; 3-state

The 74HC541; 74HCT541 is an octal non-inverting buffer/line driver with 3-state outputs. The device features two output enables (OE1 and OE2). A HIGH on OEn causes the outputs to assume a high-impedance OFF-state. Inputs include clamp diodes that enable 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

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

  • Non-Inverting outputs

  • Complies with JEDEC standards:

    • JESD8C (2.7 V to 3.6 V)

    • JESD7A (2.0 V to 6.0 V)

  • Input levels:

    • For 74HC541: CMOS levels

    • For 74HCT541: TTL levels

  • ESD protection:

    • HBM JESD22-A114F exceeds 2 kV

    • MM JESD22-A115-A exceeds 200 V

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