SEMICONDUCTOR TECHNICAL DATA
Differential Receiver
The MC100L VEL16 is a differential receiver. The device is functionally
equivalent to the EL16 device, operating from a low voltage supply. The
LVEL16 exhibits a wider CMR range than its EL16 counterpart. With
output transition times and propagation delays comparable to the EL16
the L VEL16 is ideally suited for interfacing with high frequency sources at
3.3V supplies.
The L VEL16 provides a VBB output for either single-ended use or as a
DC bias for AC coupling to the device. The VBB pin should be used only
as a bias for the LVEL16 as its current sink/source capability is limited.
Whenever used, the VBB pin should be bypassed to ground via a 0.01µf
capacitor.
Under open input conditions, the Q input will be pulled down to Vee and
the Q
input will be biased to VCC/2. This condition will force the Q output
low.

1. Duty cycle skew is the difference between a TPLH and TPHL propagation delay through a device.
2. Minimum input swing for which AC parameters guaranteed. The device has a DC gain of ≈40.
3. The CMR range is referenced to the most positive side of the differential input signal. Normal operation is obtained if the HIGH level falls within
the specified range and the peak-to-peak voltage lies between VPPmin and 1V. The lower end of the CMR range varies 1:1 with VEE. The
numbers in the spec table assume a nominal VEE = –3.3V . Note for PECL operation, the V
