STMicroelectronics 1 Surface Counter SO, 14-Pin

The HCF4093 consists of four Schmitt trigger circuits. Each circuit function has a 2-input NAND gate with Schmitt trigger action on both inputs. The gate switches at different points for positive and negative going signals. The difference between the positive voltage (VP) and the negative voltage (VN) is defined as hysteresis voltage (VH).

Hysteresis voltage typically 0.9 V at VDD = 5 V and 2.3 V at VDD =10 V

Noise immunity greater than 50 % of VDD ( typ.)

No limit on input rise and fall times

Quiescent current specified up to 20 V

Standardized symmetrical output characteristics

5 V, 10 V, and 15 V parametric ratings

Input leakage current II= 100 nA (max.) at VDD = 18 V and TA= 25 °C

100 % tested for quiescent current

ESD performance

HBM: 2 kV

MM: 200 V

CDM: 1 kV
