Communication interface chip UART485/232

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 over the full supply range from VCC to VEE. The pin-out of the HC4051A, HC4052A and HC4053A is identical 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 device designs are also more linear in on-resistance (RON) with respect to input voltage than metal-gate CMOS analog switches. For multiplexer/demultiplexers with inhibit current protection, see HC4851A and HC4852A.
