FUNCTIONAL DESCRIPTION
PIN DESCRIPTIONS
The 3D7215 5-Tap Delay Line product family consists of fixed-delay 5V
IN Delay Line Input
CMOS integrated circuits. Each package contains a single delay line,
O1 Tap 1 Output (20%)
tapped and buffered at 5 points spaced uniformly in time. Tap-to-tap
O2 Tap 2 Output (40%)
(incremental) delay values can range from 1ns through 50ns. The input O3 Tap 3 Output (60%)
is reproduced at the outputs without inversion, shifted in time as per the
O4 Tap 4 Output (80%)
user-specified dash number. The 3D7215 is 5V CMOS-compatible and O5 Tap 5 Output (100%)
features both rising- and falling-edge accuracy.
VDD +5 Volts
GND Ground
The all-CMOS 3D7215 integrated circuit has been designed as a
N/C No Connection
reliable, economic alternative to hybrid fixed delay lines. It is offered in
a standard 8-pin auto-insertable DIP and a space saving surface mount 8-pin SOIC.
