Description

The SN28846 serial driver is a monolithic CMOS integrated circuit designed to drive the serial-register gate (SRGn) and transfer-gate (TRG) inputs of the Texas Instruments (TIE) virtual-phase CCD image sensors. The SN28846 interfaces a user-defined timing generator to the CCD image sensor; it receives TTL signals from the timing generator and outputs level-shifted signals to the image sensor.The SN28846 contains three noninverting serial-gate drivers and one noninverting transfer-gate driver.

The voltage levels on SRG1OUT, SRG2OUT, SRG3OUT, and TRGOUT are controlled by the levels on VSS and VCC. The propagation delays for these outputs are controlled by SEL0 and SEL1. The PD, SRG1IN, SRG2IN,SRG3IN, and TRGIN are TTL compatible.A high level on PD allows the SN28846 to operate normally with the level-shifted outputs following the inputs.When PD is low, the device is in a low power-consumption mode and all outputs are at VCC.

The SN28846 is available in a 20-pin surface-mount package and is characterized for operation from 20 to 45.
