s
Available in 28-pin PLCC package
The SY10/100H603 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. Latching is controlled by Latch Enable
(LEN) and Master Reset (MR) resets the latches. A HIGH
on OEECL sends the outputs into the high impedance
state. All control inputs are ECL level.
The 10H version is compatible with MECL 10KH ECL
logic levels. The 100H version is compatible with 100K
levels.
