DESCRIPTION
PIN CONNECTION AND IEC LOGIC SYMBOLS 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. For operation as a digital multiplexer/demultiplexer, VEE is connected to GND. A, B and C control inputs select one of a pair of channels, they are compatible with TTL output level. All inputs are equipped with protection circuits against static discharge and transient excess voltage. September 2001 1/12 M74HCT4053 CONTROL INPUT EQUIVALENT CIRCUIT PIN DESCRIPTION
