TLC556CD Datasheet PDF - TI

The TLC556CD is a Dual LinCMOS™ Timer provides full compatibility with CMOS, TTL and MOS logic and operates at frequencies up to 2MHz. Accurate time delays and oscillations are possible with smaller, less-expensive timing capacitors than the NE556 because of the high input impedance. Power consumption is low across the full range of power supply voltages. A threshold level approximately two-thirds of the supply voltage. These levels can be altered by use of the control voltage terminal. When the trigger input falls below the trigger level, the flip-flop is set and the output goes high. If the trigger input is above the trigger level and the threshold input is above the threshold level, the flip-flop is reset and the output is low. The reset input can override all other inputs and can be used to initiate a new timing cycle. If the reset input is low, the flip-flop is reset and the output is low.

● Very low power consumption

● Capable of operation in a stable mode

● CMOS output capable of swinging rail to rail

● High output-current capability

● Low supply current reduces spikes during output transitions

● Green product and no Sb/Br
