System ground.
Enable control input. A logic low allows normal operation; a logic high puts the device into
power down mode. No output levels are defined in powerdown nor does the output behave
as a high impedance.
Output Enable input. A logic low sets the output to low-impedance driver mode; a logic high
places the output into a high-impedance state.
Lower analog control input. When Data = OE = E = L, the V
(assuming V
System power supply. The EL2021 uses this pin as a negative output current monitor connection.
Little current is drawn from this pin, transient or static.
Negative output current monitor input.
Negative power supply. Because all negative output drive currents come from this pin
(as much as 60mA transiently), good bypassing is essential.
Output to external pnp transistor base.
High-current input and output, depending on OE.
Output to external npn transistor base.
Logic output which signals that a high + or - output current is flowing.
Positive power supply. Like V-, it should be well bypassed.
Positive output current monitor input.
System power supply, similar to B-.
Higher analog control input. When Data = H and OE = E = L, the V
V
Slew rate control input. A 1V level on this pin causes the output to slew at 100V/µs, 0.5V
causes a slew rate of 50V/µs, etc.
Output level control input. This pin digitally selects V
when OE = E = L.
Not Connected.
