| QUAD DIFFERENTIAL AND/NAND SY10E404 SY100E404 FEATURES s Differential D and Q s Extended 100E VEE range of -4.2V to -5.5V s s s s s 700ps max. propagation delay High frequency outputs Internal 75K input pull-down resistors Fully compatible with Motorola 10E/100E404 Available in 28-pin PLCC package DESCRIPTION The SY10/100E404 are 4-bit differential AND/NAND devices. The differential operation of these devices make them ideal for pulse shaping applications where duty cycle skew is critical. Special design techniques were incorporated to minimize the skew between the upper and lower level gate inputs. Because a negative 2-input NAND function is equivalent to a 2-input OR function, the differential inputs and outputs of the devices also allow for their use as fully differential 2-input OR/NOR functions. The output RISE/FALL times of these devices are significantly faster than most other standard ECLinPS devices, resulting in an increased bandwidth. The differential inputs have clamp structures which will force the Q output of a gate in an open input condition to go to a LOW state. Thus, inputs of unused gates can be left open and will not affect the operation of the rest of the device.

Differential input voltage required to obtain a full ECL swing on the outputs. 2. VCMR is referenced to the most positive side of the differential input signal. Normal operation is obtained when the input signals are within the VCMR range and the input swing is greater than VPP (min.) and <1V.
