Circuit diagram
This module is used to display sign and overflow (±1). The
display is operated by the BCD code in positive logic. A
control signal (input EL) makes it possible to freeze the
display without inhibiting the BCD input signals. TTL and
CMOS logic models are available. The inputs of CMOS model
are terminated with resistors.
Caution
The terminals of the TTL and CMOS models are not identical.
Terminal 12* can be used to separately power the LED
display in the TTL model. However, it must be specified in the
order (see ordering data).
Observe the General handling directions for CMOS logic
elements (s. page 2).
