74AVC16244
10476A 3-STATE 1.8 Volt Data Pod
Output type 74AVC16244
3-state enable negative true, 38K Ω to GND, enable on no connect
Maximum clock 300 MHz
Skew (note 1) typical < 1.5 ns; worst case = 2 ns
Recommended lead set Agilent 10498A
74AVC16244
10483A 3-STATE 3.3 Volt Data Pod
Output type 74AVC16244
3-state enable negative true, 38K Ω to GND, enable on no connect
Maximum clock 300 MHz
Skew (note 1) typical < 1.5 ns; worst case = 2 ns
Recommended lead set Agilent 10498A
74AVC16244
Note 1: Typical skew measurements made at pod connector with approximately 10 pF/50 k Ω load to GND; worst case skew
numbers are a calculation of worst case conditions through circuits.
Note 2: Channel 7 on the 3-state pods has been brought out in parallel as a non 3-state signal. By looping this output back into
the 3-state enable line, the channel can be used as a 3-state enable.

Data Cable Characteristics Without a Data Pod
The Agilent pattern generator data cables without a data pod provide an ECL terminated (1 K Ω to
–5.2V) differential signal (from a type 10E156 or 10E154 driver). These are usable when received
by a differential receiver, preferably with a 100
Ω termination across the lines. These signals
should not be used single ended due to the slow fall time and shifted voltage threshold (they are
not ECL compatible).
