HD74HC292/HD74HC294
Programmable Frequency Divider/Digital Timer
Description
This device divides the incoming clock frequency by a number (a power of 2) that is preset by the
Programming inputs. It has two Clock inputs, either of which may be used as a clock inhibit. The device
also has an active-low Reset, which initializes the internal flip-flop states. Test Point outputs (TP1, TP2,
TP3) are provided with HD74HC292 to facilitate incoming inspections.
Test Point output is provided with HD74HC294 to facilitate incoming inspections.
Features
• High Speed Operation: tpd (Clock to Q) = 16 ns typ (CL = 50 pF)
• High Output Current: Fanout of 10 LSTTL Loads
• Wide Operating Voltage: VCC = 2 to 6 V
• Low Input Current: 1 µA max
• Low Quiescent Supply Current: ICC (static) = 4 µA max (Ta = 25°C)
