CD4093B is a voltage output dual D flip-flop manufactured by Texas Instruments.
The CD4093B is a CMOS quad 2‑input NAND Schmitt‑trigger device offering built‑in hysteresis on each input without external components. It provides noise immunity greater than 50% and is suitable for wave and pulse shaping, monostable and astable multivibrators, and high‑noise‑environment systems.
The datasheet includes detailed static and dynamic electrical characteristics, recommended operating conditions, and extensive package information for PDIP, SOIC, TSSOP, and NS packages, along with mechanical drawings and RoHS compliance details.
| Hysteresis voltage (typical) | 0.9 V at VOP = 5 V, 2.3 V at VOP = 10 V |
|---|---|
| Noise immunity | > 50 % |
| Maximum input current | 1 A at 18 V |
| Supply voltage range | 3 V to 18 V |
| Input capacitance (any input) | 5 pF |
| Propagation delay time (typical) | 5 ns |
The typical hysteresis voltage is 0.9 V at a 5 V supply and about 2.3 V at a 10 V supply.
The CD4093B is available in PDIP, SOIC, TSSOP (PW/PWR), and NS (plastic) packages, each with 14 leads.
Mechanical dimensions are provided in the Mechanical Data section, with all linear dimensions given in inches (and millimeters).
