Low Power 8-Bit Buffer with Cut-Off Drivers
100352 Low Power 8-Bit Buffer with Cut-Off Drivers October 1989 Revised August 2000 100352 Low Power 8-Bit Buffer with Cut-Off Drivers General Description Features The 100352 contains an 8-bit buffer, individual inputs (D ),Cut-off drivers n outputs (Q ), and a data output enable pin (OEN). A Q out-Drives 25Ω load n put follows its D input when the OEN pin is LOW. A HIGHLow power operation on OEN holds the outputs in a cut-off state. The cut-off 2000V ESD protection state is designed to be more negative than a normal ECL Voltage compensated operating range = −4.2V to −5.7V LOW level. This allows the output emitter-followers to turn Available to industrial grade temperature range off when the termination supply is −2.0V, presenting a high impedance to the data bus. This high impedance reduces termination power and prevents loss of low state noise margin when several loads share the bus. The 100352 outputs are designed to drive a doubly termi- nated 50Ω transmission line (25Ω load impedance). All inputs have 50 kΩ pull-down resistors.
