DESCRIPTION

· The 74LV393 is a dual 4-stage binary ripple counter with individual clock inputs and master reset inputs.

· It features 4 buffered parallel outputs per counter.

· The counter advances on the HIGH-to-LOW transition of the clock input.

· A HIGH on the master reset input clears the counter stages and forces the outputs LOW.

· Inputs include clamp diodes, allowing the use of current limiting resistors for interfacing with voltages exceeding VCC.

FEATURES

· Optimized for low voltage applications: 1.0 V to 3.6 V.

· Accepts TTL input levels between VCC = 2.7 V and VCC = 3.6 V.

· Typical VOLP (output ground bounce) 0.8 V at VCC = 3.3 V, Tamb = 25 °C.

· Typical VOHV (output VOH undershoot) 2 V at VCC = 3.3 V, Tamb = 25 °C.

· Two 4-bit binary counters with individual clocks.

· Divide-by any binary module up to 28 in one package.

· Two master resets to clear each 4-bit counter individually.

· Complies with JEDEC standard no. 7A.

· ESD protection: HBM exceeds 2000 V, CDM exceeds 1000 V.

APPLICATIONS

· Suitable for low voltage digital systems.

· Ideal for applications requiring binary counting and division.

· Used in systems where TTL level compatibility is necessary.

· Applicable in environments requiring robust ESD protection.
