The TMC57253 is a monolithic CMOS integrated circuit designed to drive image-area gates (IAG1, IAG2), antiblooming gate (ABG), storage-area gate (SAG), and serial-register gate (SRG) of the Texas Instruments (TITM) TC255 CCD image sensor. The TMC57253 interfaces the CCD image sensor to the TI TMC57751 ASIC or user-defined timing generator; it receives TTL-input signals from the timing generator and outputs levelshifted signals to the image sensor. ABOUT follows ABIN and ABMIN and switches between VABL, VAB, and VABM. IA1OUT and IA2OUT follow IA1IN and IA2IN, respectively, and switch between GND and VIA. The SAOUT output follows the SAIN and switches GND and VS. SROUT follows SRIN and SRMIN and switches between GND, VSM, and VS.
