3¹² Series of Encoders

Holtek Semiconductor 

312 Series of Encoders

Functional Description

Operation

The 312 series of encoders begin with a four (HT6010) or a one (HT6012/HT6014) word transmission

cycle upon receipt of a transmission enable (TE for the HT6010 or D8~D11 for the HT6012/HT6014, ac-

tive low). This cycle will repeat itself as long as the transmission enable (TE or D8~D11) is held low.

Once the transmission enable returns high the encoder output completes its final cycle and then stops

as shown below.
