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 – .

VCC –

10, 15

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 –).

VCC –

4, 5,

12, 13

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.
