| 9-BIT ECL-TO-TTL WITH 3-STATE ENABLE FEATURES s s s s s s s s s s 9-bit ideal for byte-parity applications 3-state TTL outputs Flow-through configuration Extra TTL and ECL power/ground pins to minimize switching noise ECL and TTL 3-state control inputs 4.8ns max. delay into 50pF, 9.6ns into 200pF (all outputs switching) PNP TTL inputs for low loading Choice of ECL compatibility: MECL 10KH (10Hxxx) or 100K (100Hxxx) Fully compatible with Motorola MC10H/100H601 Available in 28-pin PLCC package SY10H601 SY100H601 DESCRIPTION The SY10/100H601 are 9-bit, dual supply ECL-to-TTL translators. Devices in the Micrel-Synergy 9-bit translator series utilize the 28-lead PLCC for optimal power pinning, signal flow-through and electrical performance. The devices feature a 48mA TTL output stage and AC performance is specified into both a 50pF and 200pF load capacitance. For the 3-state output disable, both ECL and TTL control inputs are provided, allowing maximum design flexibility. The 10H version is compatible with MECL 10KH ECL logic levels. The 100H version is compatible with 100K levels.
