DESCRIPTION
The MAX3318 is a dual-driver, dual-receiver, RS-232
compatible transceiver. The device features auto- power-down plus and enhanced electrostatic
discharge (ESD) protection integrated into the chip.
Driver output and receiver input are protected to ±8
kV using the IEC 61000-4-2 Air-Gap Discharge method, ±8 kV using the IEC 61000-4-2 Contact
Discharge method, and ±15 kV using the Human-
Body Model (HBM).
The device operates at a data rate of 460 kbps. The
transceiver has a proprietary low-dropout driver
output stage enabling RS-232-compatible operation
from a 2.25-V to 3-V supply with a dual charge pump.
The charge pump requires only four 0.1-μF
capacitors and features a logic-level output (READY)
that asserts when the charge pump is regulating and
the device is ready to begin transmitting.
The MAX3318 achieves a 1-μA supply current using
the auto-power-down feature. This device
automatically enters a low-power power-down mode
when the RS-232 cable is disconnected or the drivers
of the connected peripherals are inactive for more than 30 s. The device turns on again when it senses
a valid transition at any driver or receiver input. Auto
power down saves power without changes to the
existing BIOS or operating system.
This device is available in two space-saving
packages: 20-pin SSOP and 20-pin TSSOP.
