† These parameters are measured with VSS = –10.3 V, VCC = 2.1 V, VABG+ = 4.3 V, VABG– = –7 V, and with IASR connected to VCC and ABSR

connected to VABG+, both through 22-kΩ resistors.

NOTES:

2. The algebraic convention, in which the least positive (most negative) value is designated minimum, is used in this data sheet for

voltage levels only.

3. The load consists of a TC241 CCD image sensor with ABG clocked at 2 MHz using ABG mode 3 (see the TMS3471C data sheet

for details on mode 3).

4. The load consists of a TC241 CCD image sensor with IAG and SAG clocked at 2.1 MHz.

NOTE 5: IASR is connected to VCC and ABSR is connected to VABG+, both through 22-kΩ resistors. The load consists of a TC241 CCD image

sensor with ABG clocked at 2 MHz using ABG mode 3 (see the TMS3471C data sheet for details on mode 3).
