PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 4051 DESCRIPTION The M74HCT4051 is a single eight-channel analog MULTIPLEXER/DEMULTIPLEXER fabricated with silicon gate C2MOS technology and it is pin to pin compatible with the equivalent metal gate CMOS4000B series. It contains 8 bidirectional and digitally controlled analog switches. DIP SOP TSSOP ORDER CODES PACKAGE DIP SOP TSSOP TUBE T&R M74HCT4051B1R M74HCT4051M1R M74HCT4051RM13TR M74HCT4051TTR A built-in level shifting is included to allow an input range up to ±6V (peak) for an analog signal with digital control signal of 0 to 6V. VEE supply pin is provided for analog input signals. It has an inhibit (INH) input terminal to disable all the switches when high, compatible with TTL output level. For operation as a digital multiplexer/demultiplexer, VEE is connected to GND. A, B and C control inputs select one channel out of eight channels; they are compatible with TTL output level. All inputs are equipped with protection circuits against static discharge and transient excess voltage.
