description
This Schottky barrier diode bus-termination array
is designed to reduce reflection noise on memory
bus lines. This device consists of a 16-bit
high-speed Schottky diode array suitable for
clamping to VCC and/or GND.
The SN74S1053 is characterized for operation
from 0°C to 70°C.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
‡ These values apply for tw 100 µs, duty cycle 20%.
NOTE 1: For operation above 25°C free-air temperature, derate linearly at the rate of 5 m/W/°C.
