DESCRIPTION
The HCC4093B (extended temperature range) and
HCF4093B (intermediate temperature range) are
available in 14-lead dual in-line plastic or ceramic
package and plastic micropackage. The
HCC/HCF4093B consists of four Schmitt-trigger cir-
cuits. Each circuit functions as a two-input NAND
gate with Schmitt-trigger action on both inputs. The
gate switches at different points for positive and ne-
gative-going signals.
The difference between the positive voltage (V_P)
and the negative voltage (V_N) is defined as hys-
teresis voltage (VH) (see fig. 1).
