High-Performance Silicon-Gate CMOS MC74HC4051A, MC74HC4052A, and MC74HC4053A use silicon-gate CMOS technology to achieve fast propagation delay, low on-resistance, and low off-leakage current. These analog multiplexers/demultiplexers control analog voltages that vary across the entire supply range from VCC to VEE. The HC4051A, HC4052A, and HC4053A have similar pinouts to the metal gate MC14051AB, MC14052AB, and MC14053AB. The channel select input determines which analog input/output is connected to the common output/input via an analog switch. When the enable pin is high, all analog switches are off. Channel select and enable inputs are compatible with standard CMOS outputs; with pull-up resistors, they are compatible with LSTTL outputs. These devices are designed so that the on-resistance (Ron) with respect to input voltage is more linear than the Ron of metal-gate CMOS analog switches. For multiplexer/demultiplexer with injection current protection, see HC4851A and HC4852A.
