The SY100S370 is a universal demultiplexer/decode
r that can be used as either a dual 1-of-4 decoder or as a single 1-of-8 decoder and is designed for use in high-performance ECL systems. The Mode control (M) input determines the function. In the dual 1-of-4 mode, each 4-input group has a pair of active-LOW Enable (E) inputs. The Enable pins are assigned such that in the single 1-of-8 mode they can be tied together in pairs to result in two active-LOW Enable inputs. E1a will be tied to E1b and E2a to E2b. The auxiliary inputs (Hn) are used to determine whether the outputs are active-HIGH or active-LOW. The address inputs for the dual 1-of-4 mode are A0a, A1a, A0b. A2a is unused. In the 1-of-8 mode, the address inputs are A0a, A1a, A2a. The inputs on the device have 75KΩ pull-down resistors.
Additional Features
Max. propagation delay of 1200ps
IEE min. of -92mA
Industry standard 100K ECL levels
Extended supply voltage option:
VEE = -4.2V to -5.5V
Voltage and temperature compensation for improved noise immunity
Internal 75KΩ input pull-down resistors
60% faster than National or Signetics
Approximately 40% lower power than National or Signetics
Function and pinout compatible with National and Signetics F100K
Available in 28-pin PLCC package
