CD4093BC Quad 2-Input NAND Schmitt Trigger

CD4093BC

Quad 2-Input NAND Schmitt Trigger

General Description

The CD4093B consists of four Schmitt-trigger circuits.

Eac h c i r cui t fu nc t io ns as a 2- i n put N AN D g a te wi t h Sc h mit t -

trigger acti o n on both in pu ts. T he g ate switche s at differe nt

points for positive and negative-going signals. The differ-

ence between the positive (VT+) and the negative voltage

(VT−) is defined as hysteresis voltage (VH).

All outputs have equal source and sink currents and con-

form to standard B-series output drive (see Static Electrical

Characteristics).

Features

■Wide supply voltage range: 3.0V to 15V

■Sch m itt-trigger on each input

with no external components

■Noise immunity greater than 50%

■Equal source and sink currents

■No limit on input rise and fall time

■Standard B-series output drive

■Hysteresis voltage (any input) TA = 25°C

Applications

• Wave and pulse shapers

• High-noise-environment systems

• Monostable multivibrators

• Astable multivibrators

• NAND logic

Ordering Code:

Devices also available in Tape and R eel. Speci fy by appending the s uffix let t er “X” to the ordering code.

Note 1: “Absolute Maximum Ratings” are those values beyond which the

safety of the device cannot be guaranteed; they are not meant to imply that

the devices should be operated at these limits. The table of “Recom-

mended Operating Conditions” and “Electrical Characteristics” provides

conditions for act ual devi c e operation.
