Low cost & small footprint alternative for single output applications

AHC Dividers
with Oscillator

74AHC1G42xx is a xx-stage AHC divider with oscillator.
Each flip-flop stage divides the frequency by two,consequently the 74AHC1G42xx counts to 2xx.
74AHC1G42xx dividers exist in five variants:
8, 10, 12, 14 and 15-stage.

Standard logic dividers/counters (74HC4020, 74HC4040
and 74HC4060) are general purpose solutions with multiple
outputs. In many applications, only a single frequency isrequired so only one output is used. The unused outputs
result in many divider solutions being oversized.

SO16TSSOP5(SOT109-1)(SOT353-1)

To reduce the footprint of divider solutions, the74AHC1G42xx range of dedicated single output Mini Logic
dividers has been created. 74AHC1G42xx small footprint
divider solutions oﬀer speciﬁc 2xx frequency division wherexx = 01 to 16. The footprint is reduced substantially, from59.4mm2 to 4.4mm2 (from SO16 to TSSOP5).
