DESCRIPTION
FEATURES
■3.3V power supply
■PECL/TTL-to-TTL version of popular ECLinPS
E111AE/LE
■Guaranteed low skew specification
■Three-state enable
■Differential internal design
■VBB output for single-ended operation
■Extra TTL and ECL power/ground pins
■Choice of ECL compatibility: 10K or 100K
■Matched high and low output impedance
■Available in 28-pin PLCC package
The SY10/100H646L are single supply, low skew
translating 1:8 clock drivers. Devices in the Micrel 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.
