CDx4HC151, CDx4HCT151 High-Speed CMOS Logic 8-Input Multiplexer

1 Features

• Complementary data outputs

• Buffered inputs and outputs

• Fanout (over temperature range)

– Standard outputs: 10 LSTTL Loads

– Bus driver outputs: 15 LSTTL Loads

• Wide operating temp range: -55°C° to 125°C

• Balanced propagation delay and transition times

• Significant power reduction compared to LSTTL

Logic ICs

• Alternate source is Philips/Signetics

• 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 ≤ 1μA at VOL, VOH

2 Description

The ’HC151 and ’HCT151 are single 8-channel digital

multiplexers having three binary control inputs, A, B

and C and an active low enable (G) input. The three

binary signals select 1 of 8 channels. Outputs are

both inverting (W) and non-inverting (Y).
