Additional Information

  • Summary
  • Tech Specs
  • Reviews
The NTE74HC257 is a quad 2−input multiplexer in a 16−lead DIP-type package which selects four bits of data from two sources under the control of common Select Input (S). The Output Enable input (OE) is active LOW. When OE is HIGH, all of the outputs (1Y−4Y) are in the high-impedance state regardless of all other input conditions. Moving data from two groups of registers to four common output buses is a common use of the NTE74HC257. The state-of-the-Select input determines the particular register from which the data comes. It can also be used as a function generator.
  • Wide-power supply range: 2V to 6V
  • High-noise immunity: NIL = 30%, NIH = 30% of VCC at VCC = 5V
  • Buffered inputs
  • Typical propagation delay (in to output): 12ns at VCC = 5V, CL = 15pF, TA = +25°C
  • Fanout (over temp range): standard outputs 10 LS−TTL loads, bus driver outputs 15 LS−TTL loads
  • Balanced propagation delay and transition times
  • Significant power reduction compared to LS−TTL logic ICs
