POST OFFICE BOX 655303
DALLAS, TEXAS 75265
PRINCIPLES OF OPERATION
The TLS24308, TLS24310, TLS24318, and TLS24320 address channels with logic control inputs that are
CMOS compatible. For the TLS24308 and TLS24318, mode selection is indicated in Table 2 and head selection
is indicated in Table 3. For the TLS24310 and TLS24320, mode selection is indicated in Table 2 and head
selection is indicated in Table 4. All control lines are pulled up/down internally to force the device into a nonwrite
mode in case of open input.
