| Micrel, Inc. LOW-POWER HEX ECL-to-TTL TRANSLATOR DESCRIPTION SY100S325 SY100S325 FEATURES Max. propagation delay of 3.7ns IEE min. of -37mA TTL outputs Extended supply voltage option: VEE = -4.2V to -5.5V 25% faster than National's 325 Differential inputs with built-in offset Voltage and temperature compensation for improved noise immunity VBB output for single-ended use Internal 75K input pull-down resistors Function and pinout compatible with Fairchild F100K Available in 24-pin CERPACK and 28-pin PLCC packages The SY100S325 are hex TRANSLATORs for converting 100K ECL logic levels to TTL logic levels. Inputs can be used as inverting, non-inverting or differential receivers. An internal reference voltage generator provides VBB for single-ended operation or for use in Schmitt trigger applications. All inputs have 75K pull-down resistors. The outputs will go LOW when the inputs are either open or have the same potential. When used in single-ended operation, the apparent input threshold of the true inputs is 20mV to 40mV higher (positive) than the threshold of the complementary inputs. The VTTL and VEE power may be applied in either order.
