DESCRIPTION

The SY10/100H646L are single supply, low skew
translating 1:8 clock drivers. Devices in the Micrel­Synergy H600 translator series utilize the 28-lead PLCC
for optimal power pinning, signal flow-through and
electrical performance. The single supply H646L is similar
to the HA643 which is a dual supply 1:8 version of the
same function.

These devices feature a 24mA TTL output stage, with
AC performance specified into a 20pF load capacitance.

The 10H version is compatible with 10K ECL logic
levels. The 100H version is compatible with 100K levels.

NOTES:

1. Device-to-Device Skew considering HIGH-to-HIGH or LOW-to-LOW transitions at common VCC level.

2. Within-Device Skew considering HIGH-to-HIGH transitions at common VCC level.

3. Within-Device Skew considering LOW-to-LOW transitions at common VCC level.

4. All skew parameters are guaranteed but not tested.

5. Frequency at which output levels will meet a 0.8V to 2.0V minimum swing.

6. The fMAX value is specified as the minimum guaranteed maximum frequency. Actual operational maximum frequency may be greater.

7. Clock stability is the period variation between two successive rising edges.
