DESCRIPTION

FEATURES

s 9-bit ideal for byte-parity applications

s 3-state TTL outputs

s Flow-through configuration

s Extra TTL and ECL power/ground pins to minimize

switching noise

s ECL and TTL 3-state control inputs

s 4.8ns max. delay into 50pF, 9.6ns into 200pF (all

outputs switching)

s PNP TTL inputs for low loading

s Choice of ECL compatibility: MECL 10KH (10Hxxx)

or 100K (100Hxxx)

s Fully compatible with Motorola MC10H/100H601

s Available in 28-pin PLCC package

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.
