CD74HCT251E 产品详情

The ’HC251 and ’HCT251 are 8-channel digital multiplexers with three-state outputs, fabricated with high-speed silicon-gate CMOS technology. Together with the low power consumption of standard CMOS integrated circuits, they possess the ability to drive 10 LSTTL loads. The three-state feature makes them ideally suited for interfacing with bus lines in a bus-oriented system.

This multiplexer features both true (Y) and complement (Y\) outputs as well as an output enable (OE\) input. The OE\ must be at a low logic level to enable this device. When the OE\ input is high, both outputs are in the high-impedance state. When enabled, address information on the data select inputs determines which data input is routed to the Y and Y\ outputs. The ’HCT251 logic family is speed, function, and pin-compatible with the standard ’LS251.

Feature

  • Selects One of Eight Binary Data Inputs
  • Three-State Output Capability
  • True and Complement Outputs
  • Typical (Data to Output) Propagation Delay of 14ns at VCC = 5V, CL = 15pF, TA = 25°C

    • Standard Outputs . . . . . . . . . . . . . . . 10 LSTTL Loads
    • Bus Driver Outputs . . . . . . . . . . . . . 15 LSTTL Loads
  • Wide Operating Temperature Range . . . -55°C to 125°C
  • Balanced Propagation Delay and Transition Times
  • Significant Power Reduction Compared to LSTTL Logic ICs
  • Alternate Source is Philips
  • HC Types
    • 2V to 6V Operation
    • High Noise Immunity: NIL = 30%, NIH = 30% of VCC at VCC = 5V
  • HCT Types
    • 4.5V to 5.5V Operation
    • Direct LSTTL Input Logic Compatibility, VIL = 0.8V (Max), VIH = 2V (Min)
    • CMOS Input Compatibility, Il1μA at VOL, VOH
