Active low output that indicates if lcl valid RS levels are present on any receiver input. Small footprint packaging, and the use of small, low value capacitors ensure board space savings as well. 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?

Guaranteed Minimum Slew Rate. This micro-power mode makes these devices ideal for battery powered and portable applications. All Transmitter Outputs Loaded with 3k? In ivl 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.

Table 2 summarizes the automatic powerdown functionality. ICLX monitor receivers remain active even during manual powerdown and forced receiver disable, making them extremely useful for Ring Indicator monitoring. Figure 10 ixl a transmitter loopback test circuit, and Figure 11 illustrates the loopback test result at kbps. The power management logic then uses this indicator ifl power down the interface block. In powerdown, supply current drops to 1? Active low input to shut down transmitters and on-board power supply, to place device in low power mode.

F; Unless Otherwise Speci? INVALID operates in all modes forced or automatic powerdown, or forced onso it is also useful for systems employing manual powerdown circuitry. Driving EN high disables all the inverting standard receiver outputs placing them in a high impedance state.

Data rates greater than kbps are guaranteed at worst case load conditions. The circuit is divided into three sections: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.

Standard receivers driving powered down peripherals must be disabled to prevent current? The charge pumps operate discontinuously i. Reconnecting the cable restores valid levels at jcl receiver inputs, INVALID switches high, and the power management logic wakes up the interface block.

In the case of a disconnected interface cable where all the receiver inputs are? For this test, all transmitters were simultaneously driving RS loads in parallel with pF, at kbps. Figure 12 shows the loopback results for a single transmitter driving pF and an RS load at kbps.

External capacitor voltage doubler is connected to this lead. As they activate, the two transmitter outputs properly go to opposite RS levels, with no glitching, ringing, nor undesirable transients. Connect the bypass capacitor as close as possible to the IC. RS compatible receiver inputs. See Table 4 for more information on possible combinations of interconnections. Additionally, the two ICLX products include noninverting monitor receivers denoted by the ROUTB label that are always active, regardless of the state of any control lines.

For other supply voltages refer to Table 3 for capacitor values.

The static transmitters were also loaded with an RS receiver. Note that the transmitters enable only when the magnitude of the supplies exceed approximately 3V. This renders them useless for wake up functions, but the corresponding monitor receiver can be dedicated to this task as shown in Figure 3.

F bypass capacitor is adequate.
