• Manufacturer Part Number: ds1124
• Description: Ds1124 5.0v 8-bit Programmable Timing Element
• Manufacturer: Maxim Integrated Products, Inc.

Input:
Ambient Temperature:
Supply Voltage (V
Input Pulse:
Source Impedance:
Rise and Fall Times:
Pulse Width:
Period:
Output: The outputs are loaded with 15pF. Delay is
measured between the 1.5V level of the rising or falling
edge of the input signal and the corresponding edge of
the output signal.
Note: Above conditions are for test only and do not
restrict the operation of the device under other data
sheet conditions.
