MC145705 Product details

Description

VCC Digital Power Supply This digital supply pin is connected to the logic power supply. 232 D connector (Pin 7) as well as to the logic power supply ground. chip voltage doubler and the positive power supply input of the driver/receiver sections of the device.

Features

er sections of the device. This pin requires an external storage capacitor to filter the 50% duty cycle voltage generated by the charge pump. TxEN Output Enable This is the driver output enable pin. When this pin is in logic low level, the condition of the driver outputs (Tx1.
Tx3) are in keep OFF (mark) state. STB Standby The device enters the standby mode while this pin is connected to the logic high level. During the standby mode, driver and receiver output pins become high impedance.
