Driving Relays with CMOS and TTL Outputs Calculator This calculator will help find a suitable switching transistor, and provide a value for the base resistor that will sufficiently saturate the transistor.  · TTL And CMOS Logic ICs: The Building Blocks Of A Revolution. When starting a new electronics project today, one of the first things that we tend . VOLmax of the driver gate TTL HIGH output (VOH min of V) is not suitable as HIGH input to a CMOS gate (VIH min of V).

CMOS (complementary metal oxide silicon) devices defeat most of the disadvantages associated with common TTL devices, but while in doing this, add a few of their own. CMOS ICs are popular due to their incredibly reduced standby current consumption. Applications: TTL/CMOS Clock Distribution Fanout Line Drivers 1 PPS Distribution/IRIG-B Distribution High Speed Digital Communications System Testing Essential Lab Tool Features: fmax gt; MHz Drives ft of cable @ 80 MHz 2 ns Typical Output Rise amp; Fall Times TTL Compatible 50 Ω or 1 kΩ Input ps typical channel to channel skew Four in-phase 50 Ω TTL Outputs BNC or SMA I/O. The pin features TTL/CMOS-compatible thresholds. 2 PWM_1 PWM input signal for Driver 1 featuring TTL/CMOS-compatible threshold and hysteresis. Even though internally pulled down to GND with a 10 μA current generator, it is recommended to pull-down to GND with an external kΩ resistor. 3 GND.

Following figure shows a CMOS gate driving N TTL gates. For such an arrangement to operate properly the following conditions are required to be satisfied. current into the ON/OFF pin is so low, TTL or CMOS drivers have no problem controlling the device. The strobe pin is not fully logic compatible. Also the circuit driving the AND gate's inputs only needs to supply current to one single input, as the fan-in is “1”. Interfacing TTL to CMOS devices would.
