MAX3320A Datasheet (Maxim) - up to 250kbps True RS-232 Transceiver

MAX3320A, up to 250kbps True RS-232 Transceiver

The MAX3320 combines a microprocessor (µP) supervisory circuit with an RS-232 transceiver.

The power-on reset performs a single function: it asserts a reset signal whenever the VCC supply voltage declines below a preset threshold, staying asserted for at least 100ms after VCC rises above the reset t
