MC10E1651FNR2G Comparators

The MC10E1651 is functionally and pin-for-pin compatible with the MC1651 in the MECL III family, but is fabricated using Motorola's advanced MOSAIC III process. The MC10E1651 incorporates a fixed level of input hysteresis as well as output compatibility with 10KH logic devices. In addition, a latch is available allowing a sample and hold function to be performed. The device is available in both a 16-pin DIP and a 20-pin surface mount package.

The latch enable (LEN_abar and LEN_bbar) input pins operate from standard ECL 10KH logic levels. When the latch enable is at a logic high level the MC10E1651 acts as a comparator, hence Q will be at a logic high level if V1 > V2 (V1 is more positive than V2). Qbar is the complement of Q. When the latch enable input goes to a low logic level, the outputs are latched in their present state providing the latch enable setup and hold time constraints are met.

The 100 series contains temperature compensation.
