Overview
CD54HC251, CD74HC251, CD54HCT251, CD74HCT251 SCHS169D – NOVEMBER 1998 – REVISED MARCH 2022 CDx4HC251, CDx4HCT251 High-Speed CMOS Logic 8-Input Multiplexer, Three-State 1 Features • Selects one of eight binary data inputs • Three-state output capability • True and complement outputs • Typical (data to output) propagation delay of 14 ns at VCC = 5 V, CL = 15 pF, TA = 25 ℃ • Fanout (over temperature range) – Standard outputs : 10 LSTTL loads – Bus driver outputs : 15 LSTTL loads • Wide operating temperature range : – 55 ℃ to 125 ℃ • Balanced propagation delay and transition times • Significant power reduction compared to LSTTL logic ICs • Alternate source is Philips • HC types – 2 V to 6 V operation – High noise immunity : NIL = 30 %, NIH = 30% of VCC at VCC = 5 V • HCT types – 4.
5 V to 5.
5 V operation – Direct LSTTL input logic compatibility, VIL = 0.
8 V (Max), VIH = 2 V (Min) – CMOS input compatibility, II ≤ 1 μA at VOL, VOH OE S0 S1 S2 2 Description The ’HC251 and ’HCT251 are 8-channel digital multiplexers with three-state outputs, fabricated with high-speed silicongate 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 busoriented system.
