_______________Detailed Description
Dual Charge-Pump Voltage Converter
The MAX3384E’s internal power supply consists of a
regulated dual charge pump that provides output volt-
ages of +5.5V (doubling charge pump) and -5.5V
(inverting charge pump), over the +3.0V to +5.5V V
CC
range. The charge pump operates in discontinuous
mode; if the output voltages are less than 5.5V, the
charge pump is enabled, and if the output voltages
exceed 5.5V, the charge pump is disabled. Each
charge pump requires a flying capacitor (C1, C2) and a
reservoir capacitor (C3, C4) to generate the V+ and V-
supplies (Figure 1).
RS-232 Transmitters
The transmitters are inverting level translators that con-
vert CMOS-logic levels to ±5.0V EIA/TIA-232 levels.
The MAX3384E transmitters guarantee a 250kbps data
rate with worst-case loads of 3k
in parallel with 1000pF,
providing compatibility with PC-to-PC communication
software (such as LapLink). Transmitters can be paral-
leled to drive multiple receivers or mice.
The MAX3384E’s transmitters are disabled and the out-
puts are forced into a high-impedance state when the
device is in shutdown (
SHDN
= GND). The MAX3384E
permits the outputs to be driven up to ±12V in shut-
down.
The transmitter inputs do not have pullup resistors.
Connect unused inputs to GND or V
CC
.
RS-232 Receivers
The receivers convert RS-232 signals to CMOS-logic
output levels (Table 1). The receiver outputs are forced
into a high-impedance state when the device is in shut-
down (
SHDN
= GND). This allows a single UART to
multiplex between different protocols.
Shutdown Mode
Supply current falls to less than 1μA in shutdown mode
(
SHDN
= low). When shut down, the device’s charge
