? 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 (T D ) and the characteristic impedance of the line (Z) are determined by the dash number. The rise time (T R ) of the line is 30% of T D , and the 3dB bandwidth is given by 1.05 / T D . 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 290mil DIP, 100ns, 50? delay line with pinout code B.Similarly, 1516SB-151-501 is a 240 mil SMD, 150ns,500? delay line with standard pinout.
