DS3690 Maxim, DS3690 Datasheet - Page 3

• Manufacturer Part Number: DS3690
• Description: The DS3690 is a 26-channel, three-stateable transmission gate designed for transparent digital signal transfer when enabled and fast-gated bus isolation when the device is disabled
• Manufacturer: Maxim

Figure 2. Digital Channels Enabled by CE
Note 1: All voltages referenced to ground.
Note 2: Typical waveform shown is labeled CHxxA (input) to CHxxB (output), and is identical in function when selecting pin CHxxB
Note 3: Output reference level is V
Note 4: Input transitions prior to the CE falling edge are ignored (don’t care).
Note 5: Propagation delay differential between any two channels when using a common input signal source.
Note 6: Guaranteed by design and not 100% tested.
