Data on the select inputs (1A0 and 1A1 or 2A0 and 2A1) cause one of the four normally high outputs to go low. If the enable input is high all four outputs remain high. For demultiplexer operation the enable input is the data input. The enable input also functions as a chip select when these devices are cascaded. This device is functionally the same as the CD4556B and is pin compatible with it. The outputs of these devices can drive 10 low power Schottky TTL equivalent loads. The HCT logic family is functionally as well as pin equivalent to the LS logic family. 14 15 16 9 13 12 11 10 1 2 3 4 5 7 6 8 1E 1A0 1A1 1Y0 1Y1 1Y2 GND 1Y3 VCC 2A0 2A1 2Y0 2Y1 2Y2 2Y3 2E Ordering Information PART NUMBER TEMP.
