PRINCIPLES OF OPERATION
The TLS24302 and TLS24306 addresses channels with logic control inputs that are CMOS compatible. For the
TLS24306, mode selection is indicated in Table 2 and head selection is indicated in Table 3. When using the
TLS24302, only heads 0 and 1 are selected. All control lines are pulled up/down internally to force the device
into a nonwrite mode in case of open input.

NOTE 6: HS2, HS1, and HS0 are available in the TLS24306 only and all are pulled up
internally. The TLS24302 has one head select (HS) terminal and it is pulled up
internally.
