100352
Low Power 8-Bit Buffer with Cut-Off Drivers
General Description
The 100352 contains an 8-bit buffer, individual inputs (D
n
),
outputs (Q
n
), and a data output enable pin (OEN). A Q out-
put follows its D input when the OEN pin is LOW. A HIGH
on OEN holds the outputs in a cut-off state. The cut-off
state is designed to be more negative than a normal ECL
LOW level. This allows the output emitter-followers to turn
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.
Features
a73 Cut-off drivers
a73 Drives 25Ω load
a73 Low power operation
a73 2000V ESD protection
a73 Voltage compensated operating range = −4.2V to −5.7V
a73 Available to industrial grade temperature range
