2 Comparing the MC44BS374CA to the MC44BC374C
Compared to the MC44BC374C devices, the MC44BS374CA has the following improvements:
Higher output level (82 dBuV versus 74.5 dBuV)
Higher Video signal to noise (+ 3 dB)
I
2
C-bus 3.3V compatible
Lower power consumption in normal and standby modes (-2 mA)
The device can be powered down without holding the I
2
C lines down.
TB1 bit is no more available (limited compatibility with MC44355 devices no more available)
Switch between the two integrated VCO’s controlled directly by the frequency divider (@ 700
MHz)
