*Add “-T” suffix to part number for tape and reel packaging.
NOTE: Intersil Pb-free products employ special Pb-free material
sets; molding compounds/die attach materials and 100% matte tin
plate termination finish, which is compatible with both SnPb and
Pb-free soldering operations. Intersil Pb-free products are MSL
classified at Pb-free peak reflow temperatures that meet or exceed
the Pb-free requirements of IPC/JEDEC J Std-020B.
Pin Descriptions
PIN
FUNCTION
VCC
System power supply input (3.0V to 5.5V).
V+
Internally generated positive transmitter supply (+5.5V).
V-
Internally generated negative transmitter supply (-5.5V).
GND
Ground connection.
C1+
External capacitor (voltage doubler) is connected to this lead.
C1-
External capacitor (voltage doubler) is connected to this lead.
C2+
External capacitor (voltage inverter) is connected to this lead.
C2-
External capacitor (voltage inverter) is connected to this lead.
TIN
TTL/CMOS compatible transmitter Inputs (Note 2).
TOUT
±15kV ESD Protected, RS-232 level (nominally ±5.5V) transmitter outputs.
RIN
±15kV ESD Protected, RS-232 compatible receiver inputs.
ROUT
TTL/CMOS level receiver outputs.
ROUTB
TTL/CMOS level, noninverting, always enabled receiver output.
EN
Active low receiver enable control; doesn’t disable ROUTB output (Note 2).
SHDN
Active low input to shut down transmitters and on-board power supply, to place device in low power mode (Note 2).
MBAUD
Input low selects 250kbps data rate, and input high selects 1Mbps data rate (Note 2).
NOTE:
2. These input pins incorporate positive feedback resistors. Once the input is driven to a valid logic level, the feedback resistor maintains that logic
level until VCC is removed.
