CD74ACT241: Typo in datasheet

Part Number: CD74ACT241

Tool/software:

Figures 3-2 and 3-3 contradict Table 3-1 in the datasheet for this part regarding pin 3

The Figures indicate the pin 3 nomenclature is 2Y0 (the same as pin 9). 

Table 3-1 indicates the pin 3 nomenclature is 2Y3.

The absence of pin nomenclature 2Y3 in the Figures is conspicuous and implies there is no output for the buffer input 2A3 on pin 17.  It also implies there are 2 outputs (pins 3 and 9, both 2Y0) associated with buffer input on pin 2 (1A0).

Please confirm the nomenclature for pin 3 (2Y0) in Figs 3-2 and 3-3 is an error and should be 2Y3 like in the Table.  

  • All 74xxx241/74xxx244 devices use a standard pinout. Table 3-1 is correct; figures 3-2 and 3-3 are wrong.

    The CD74xxx devices were acquired from Harris Semiconductor in 1998, and the pinout figures are scans of the old datasheet. Apparently, these errors have been present for a long time.
