MC10E1652 Datasheet, PDF (1/7 Pages) ON Semiconductor – DUAL ECL OUTPUT COMPARATOR WITH LATCH
MOTOROLA
SEMICONDUCTOR TECHNICAL DATA
Dual ECL Output Comparator
With Latch
The MC10E1652 is functionally and pin-for-pin compatible with the
MC10E1651 and thus the MC1651 in the MECL III™ family, but is
fabricated using Motorola’s advanced MOSAIC III™ process and is output
compatible with 10H logic devices. In addition, the device is available in
both a 16-pin DIP and a 20-pin surface mount package. However, the
MC10E1652 provides user programmable hysteresis.
The latch enable (LENa and LENb) input pins operate from standard
ECL 10H™ logic levels. When the latch enable is at a logic high level the
MC10E1652 acts as a comparator, hence Q will be at a logic high level if
V1 > V2 (V1 is more positive than V2). Q 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 level of input hysteresis is controlled by applying
a bias voltage to the HYS pin.
• Typical 3.0 dB Bandwidth > 1.0 GHz

• Typical Output Rise/Fall of 350 ps
• Common Mode Range –2.0 V to +3.0 V
• Individual Latch Enables
• Differential Outputs
• Programmable Input Hysteresis
