Operation Down to 2.7V
The ISL4241E, ISL4243E transmitter outputs meet RS-562
levels (±3.7V), at the full data rate, with VCC as low as 2.7V.
RS-562 levels typically ensure inter operability with RS-232
devices.
High Data Rates
The ISL4241E, ISL4243E maintain the RS-232 ±5V
minimum transmitter output voltages even at high data rates.
Figure 9 details a transmitter loopback test circuit, and
Figure 10 illustrates the loopback test result at 120kbps. For
this test, all transmitters were simultaneously driving RS-232
loads in parallel with 1000pF, at 120kbps. Figure 11 shows
the loopback results for a single transmitter driving 1000pF
and an RS-232 load at 250kbps. The static transmitters were
also loaded with an RS-232 receiver.
Interconnection with 3V and 5V Logic
The ISL4241E, ISL4243E directly interface with 5V CMOS
and TTL logic families. Nevertheless, with the ISL4241E,
ISL4243E at 3.3V, and the logic supply at 5V, AC, HC, and
CD4000 outputs can drive ISL4241E, ISL4243E inputs, but
ISL4241E, ISL4243E outputs do not reach the minimum VIH
for these logic families. See Table 3 for more information.
