• Delays to 200ns
• Low profile
• Epoxy encapsulated
• Meets or exceeds MIL-D-23859C
FUNCTIONAL DESCRIPTION
The 1516-series device is a fixed, single-input, five-
output, passive delay line. The signal input (IN) is
reproduced at the outputs (T1-T5) in equal increments.
The delay from IN to T5 (TD) and the characteristic
impedance of the line (Z) are determined by the dash
number. The rise time (TR) of the line is 30% of TD, and
the 3dB bandwidth is given by 1.05 / TD. The device is
available in a 8-pin DIP (1516) or a 8-pin SMD (1516S),
and a wide range of pinouts may be specified.
Part numbers are constructed according to the scheme
shown at right. For example, 1516C-101-500B is a 290
mil DIP, 100ns, 50Ω delay line with pinout code B.
Similarly, 1516SB-151-501 is a 240 mil SMD, 150ns,
500Ω delay line with standard pinout.
