TRS1 and TRS2 are 3-state input terminals. TRS2 should be connected to the ground of the circuit generating the 3-state
command (normally µP ground). The TLE2301 is brought into 3-state mode by raising TRS1 2 V above TRS2. Placing the
TLE2301 in a 3-state mode reduces the supply current to below 2.2 mA (typ). Normal operation resumes by bringing TRS1
to within 0.8 V of TRS2. The 3-state function can be disabled by connecting both TRS1 and TRS2 to VCC _– .
High-impedance VCC _– input terminals. Although these do not carry any of the device’s supply current, they increase the
stability of the device and should be connected to the negative supply terminal (VCC _–).
Negative supply terminals and substrate. As with all NE packages, the substrate is directly connected to the lead frame.
The result is that the junction-to-ambient thermal impedance (Z_θJA) is greatly reduced by soldering the negative supply
terminals to the copper area of the printed-circuit board (PCB).
VCC ₊
2, 7 Positive supply terminals. Both terminals should be connected to the positive voltage supply.
