Supply original MC14538BDWR2G, Logic - Multivibrators, by ON Semiconductor

The MC14538B is a dual, retriggerable, resettable monostable multivibrator. It may be triggered from either edge of an input pulse, and produces an accurate output pulse over a wide range of widths, the duration and accuracy of which are determined by the external timing components, CX and RX. Output Pulse Width T = RX
• CX (secs) RX = Ω CX = Farads
Features
• Unlimited Rise and Fall Time Allowed on the A Trigger Input
• Pulse Width Range = 10 μs to 10 s
• Latched Trigger Inputs
• Separate Latched Reset Inputs
• 3.0 Vdc to 18 Vdc Operational Limits
• Triggerable from Positive (A Input) or Negative−Going Edge (B−Input)
• Capable of Driving Two Low−Power TTL Loads or One Low−Power Schottky TTL Load Over the Rated Temperature Range
• Pin−for−pin Compatible with MC14528B and CD4528B (CD4098)
• Use the MC54/74HC4538A for Pulse Widths Less Than 10 μs with Supplies Up to 6 V
• NLV Prefix for Automotive and Other Applications Requiring Unique Site and Control Change Requirements; AEC−Q100 Qualified and PPAP Capable
