Transmitter Output when Exiting
Powerdown
Figure 3 shows the response of the transmitter output when
exiting powerdown mode. As it activates, the transmitter
output properly goes to RS-232 levels, with no glitching,
ringing, nor undesirable transients. The transmitter is loaded
with 3k
Ω in parallel with 2500pF. Note that the transmitter
enables only when the magnitude of the supplies exceed
approximately 3V.
High Data Rates
The ISL83220E maintains the RS-232 ±5V minimum
transmitter output voltages even at high data rates. Figure 4
details a transmitter loopback test circuit, and Figure 5
illustrates the loopback test result at 120kbps. For this test,
the transmitter is driving an RS-232 load in parallel with
1000pF, at 120kbps. Figure 6 shows the loopback results for
the transmitter driving 1000pF and an RS-232 load at
250kbps.
Interconnection with 3V and 5V Logic
The ISL83220E directly interfaces with 5V CMOS and TTL
logic families. Nevertheless, with the device at 3.3V, and the
logic supply at 5V, AC, HC, and CD4000 outputs can drive
ISL83220E inputs, but ISL83220E outputs do not reach the
minimum VIH for these logic families. See Table 4 for more
information.
