Pin Description (Continued)
Pin Number
Pin Name
Pin Function
42
SEL
This single-ended TTL/CMOS-compatible input selects the inputs to the multiplexer.
Note that this input is internally connected to a 25k pull-up resistor and will default
to logic HIGH state if left open. VTH = VCC/2.
1, 11, 6
GND,
Exposed Pad
Ground: Ground and exposed pad must be connected to the same ground plane.
12
CAP
Power-on-Reset (POR) initialization capacitor. When using the multiplexer with RPE
capability, this pin is tied to a capacitor to VCC. The purpose is to ensure the internal
RPE logic starts up in a known state. See “Power-On Reset (POR) Description”
section for more details regarding capacitor selection. If this pin is tied directly to VCC,
the RPE function will be disabled and the multiplexer will function as a normal
multiplexer. The CAP pin should never be left open or tied directly to GND.

EN
Single-Ended Input: This TTL/CMOS input disables and enables the Q0-Q9 outputs.
It is internally connected to a 25k pull-up resistor and will default to a logic HIGH
state if left open. When disabled, CLK output goes LOW and /CLK goes HIGH. EN
being synchronous, outputs will be enabled/disabled when they are in LOW state.
Thus, a runt pulse is avoided if the device is enabled/disabled by an asynchronous
control. VTH = VCC/2.
