SPI/MICROWIRE-Compatible UART and ±15kV ESD-
Protected RS-232 Transceivers with Internal Capacitors
Pin Description
Positive terminal of internal inverting charge-pump capacitor. Do not make any connection to this terminal.
C2+
24
Negative terminal of internal inverting charge-pump capacitor. Do not make any connection to this terminal.
C2-
25
-5.5V generated by the internal charge pump. Do not make any connection to this terminal.

RS-232 Transmitter Output 2
T2OUT
28
UART Active-Low Interrupt Output. Open-drain interrupt output to microprocessor.
IRQ
19
Hardware Shutdown Input. Drive SHDN low to shut down the RS-232 transmitters and charge pump. Drive
high for normal operation.
SHDN
20
+5.5V generated by the internal charge pump. Do not make any connection to this terminal.
V+
21
Positive terminal of the internal voltage-doubler charge-pump capacitor. Do not make any connection to
this terminal.
C1+
22
Negative terminal of the internal voltage-doubler charge-pump capacitor. Do not make any connection to
this terminal.
C1-
23
SPI/MICROWIRE Serial-Data Input. Schmitt-trigger Input.
DIN
15
SPI/MICROWIRE Serial-Data Output. High impedance when CS is high.
DOUT
16
SPI/MICROWIRE Serial-Clock Input. Schmitt-trigger input.
SCLK
17
UART Active-Low Chip-Select Input. DOUT goes high impedance when CS is high. IRQ, TX, and RTS are
always active. Schmitt-trigger input.
CS
18
UART Asynchronous Serial-Data (transmitter) Output
TX
14
UART Crystal Connection. Leave X2 unconnected when using an external CMOS clock. See the
Crystals,
Oscillators, and Ceramic Resonators section.
X2
9
UART Crystal Connection. X1 also serves as an external CMOS clock input. See the
Crystals, Oscillators,
and Ceramic Resonators section.
X1
10
UART Clear-to-Send Active-Low Input. Read via the CTS bit.
CTS
11
UART Request-to-Send Active-Low Output. Controlled by the RTS bit. Also used to control the driver enable
in RS-485 networks.
RTS
12
UART Asynchronous Serial-Data (receiver) Input. The serial information received from the RS-232 receiver.
A transition on RX while in shutdown generates an interrupt (Table 1).
