DESCRIPTION
Analog ground
I Analog input
I Clock input
Digital ground
O Digital data out. D1 = LSB, D8 = MSB
I Output enable. When OE = low, data is enabled. When OE = high, D1 – D8 is in high-impedance state.
Analog supply voltage
Digital supply voltage
I Reference voltage in bottom
Reference voltage in bottom. When using the TLC5510 internal voltage divider to generate a nominal 2-V
reference, REFBS is shorted to REFB (see Figure 3). When using the TLC5510A, REFBS is connected to
ground.
I Reference voltage in top
Reference voltage in top. When using the TLC5510 internal voltage divider to generate a nominal 2-V
reference, REFTS is shorted to REFT (see Figure 3). When using the TLC5510A, REFTS is connected to
VDDA.

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.

‡ _{The reference voltage levels for the TLC5510 are derived through an internal resistor divider between VDDA and ground and therefore are not}
derived from a separate external voltage source (see the electrical characteristics and text). For the 4 V input range of the TLC5510A, the
reference voltage is externally applied across the center divider resistor.
