HD74HC292/HD74HC294
Programmable Frequency Divider/Digital Timer
REJ03D0608 0200 (Previous ADE-205-486) Rev.2.00 Jan 31, 2006

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 uA max Low Quiescent Supply Current: ICC (static) = 4 uA max (Ta = 25 C) Ordering Information
