The IN74AC192 is identical in pinout to the LS/ALS192, HC/HCT192. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALS outputs.
The counter can be cascaded by connecting the TCU and TCD outputs of one device to the Count Up Clock and Count Down Clock inputs, respectively, of the next device.
