SY100S325Micrel, Inc. M9999-061306 hbwhelp@micrel.com or (408) 955-1690 LOW-POWER HEX ECL-to-TTL TRANSLATOR DESCRIPTIONFEATURES ■ 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 75KΩ 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 V BB for single-ended operation or for use in Schmitt trigger applications. All inputs have 75K Ω 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 V TTL and VEE power may be applied in either order.
