3V to 5.
5V, up to 250kbps True RS-232 Transceiver with 4µA AutoShutdown Plus and Power-On Reset
_______________General Description
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 threshold.
The MAX3320 has an active-low RESET output, which is guaranteed to be in the correct state for VCC down to 1V.
The reset comparator is designed to ignore fast transients on VCC.
Reset thresholds suitable for operation wi...
