Detailed Description
The ICL32X7E interface ICs operate from a single +3V to
+5.5V power supply, guarantee a 250kbps minimum data
rate, require only four small external 0.1
F capacitors,
feature low power consumption, and meet all ElA RS-232C
and V.28 specifications. The circuit is divided into three
sections: charge pump, transmitters and receivers.
Charge-Pump
Intersil’s new ICL32XXE family utilizes regulated on-chip
dual charge pumps as voltage doublers, and voltage
inverters to generate
±5.5V transmitter supplies from a VCC
supply as low as 3V. 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
F capacitors
for the voltage doubler and inverter functions at VCC =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.
ICL3217E transmitter outputs disable and assume a high
impedance state when the device enters the automatic
powerdown mode. These outputs may be driven to
±12V
when disabled.
Both 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 VCC ≥ 3.3V, RL =3k, and CL = 250pF, one
transmitter easily operates at 800kbps.
Transmitter inputs float if left unconnected, and may cause
ICC increases. Connect unused inputs to GND for the best
performance.
