Comparing the MC44BS374CA to the MC44BC374C
MC44BS374CA Technical data
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)
I2C-bus 3.3V compatible
Lower power consumption in normal and standby modes (-2 mA)
The device can be powered down without holding the I2C 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)
