This family is fully compatible with 3. If in doubt, use capacitors with a larger nominal value. The INVALID output always indicates whether or not a valid RS signal is present at any of the receiver inputs see Table 2giving the user an easy way to determine when the icll block should power down.

Active low input to shut down ivl and on-board power supply, to place device in low power mode.

In applications that are particularly sensitive to power supply noise, decouple VCC to ground with a capacitor of the same value as the charge-pump capacitor C1.

Data rates greater than kbps are guaranteed at worst case load conditions. This automatic powerdown feature provides additional system power savings without changes to the existing operating system. Low Supply Current in Powerdown State. Nevertheless, if strictly manual control over powerdown is desired, the user must strap FORCEON high to disable the automatic powerdown circuitry. RS compatible receiver inputs. Figure 12 shows the loopback results for a single transmitter driving pF and an RS load at kbps.


For other supply voltages refer to Table 3 for capacitor values. Wide Power Supply Range.

Guaranteed Minimum Data Rate. These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures. Connect the bypass capacitor as close as possible to the IC. Internally generated negative transmitter supply The ICLX are 3 driver, 5 receiver devices that provide a complete serial port suitable for laptop jcl notebook computers.

Note that all the receiver outputs remain enabled during shutdown see Table 2. Targeted applications are PDAs, Palmtops, and notebook and laptop computers where the low operational, and even lower standby, power consumption is critical. This is a stress only rating and operation of the device at these or any other conditions above those indicated in the operational sections of this speci? Inverting receiver outputs may or may not disable in powerdown; refer to Table 2 for details. INVALID operates in all modes forced or automatic powerdown, or forced onso it is also useful for systems employing manual powerdown circuitry.


For the lowest power consumption during powerdown, the receivers should also be disabled by driving the EN input high see next section, and Figures 2 and 3.

Table 2 summarizes the automatic powerdown functionality. The circuit is divided into three sections: Note that the transmitters enable only when the magnitude of the supplies exceed approximately 3V. In powerdown, supply current drops to 1?

The already low current requirement drops signi? The power management logic then uses this indicator to power down the kcl block. Do not use values smaller than those listed in Table 3. Capacitor Selection The charge pumps require 0.

Active low output that indicates if no valid RS levels are present on any receiver input.

See Table 4 for more information on possible combinations of interconnections. For this test, all transmitters were simultaneously driving RS loads in parallel with pF, at kbps.
