Detailed Description
ICL3310 interface ICs operate from a single +3V to +5.5V
supply, guarantee a 250kbps minimum data rate, require
only four small external 0.1
μ
F capacitors, feature low power
consumption, and meet all ElA RS-232C and V.28
specifications. The circuit is divided into three sections: The
charge pump, the transmitters, and the receivers.
Charge-Pump
Intersil’s new ICL3310 utilizes regulated on-chip dual charge
pumps as voltage doublers, and voltage inverters to
generate
±
5.5V transmitter supplies from a V
CC
supply as
low as 3.0V. This allows these devices to maintain RS-232
compliant output levels over the
±
10% tolerance range of
3.3V powered systems. The efficient on-chip power supplies
require only four small, external 0.1
μ
F capacitors for the
voltage doubler and inverter functions at V
CC
= 3.3V. See
the “Capacitor Selection” section, and Table 3 for capacitor
recommendations for other operating conditions. The charge
pumps operate discontinuously (i.e., they turn off as soon as
the V+ and V- supplies are pumped up to the nominal
values), resulting in significant power savings.
Transmitters
The transmitters are proprietary, low dropout, inverting
drivers that translate TTL/CMOS inputs to EIA/TIA-232
output levels. Coupled with the on-chip
±
5.5V supplies,
these transmitters deliver true RS-232 levels over a wide
range of single supply system voltages.
All transmitter outputs disable and assume a high
impedance state when the device enters the powerdown
mode (see Table 2). These outputs may be driven to
±
12V
when disabled.
All devices guarantee a 250kbps data rate for full load
conditions (3k
and 1000pF), V
CC
≥
3.0V, with one
transmitter operating at full speed. Under more typical
conditions of V
CC
≥
3.3V, R

, and C
L
= 250pF, one
transmitter easily operates at 900kbps.
