SDLS153A – JANUARY 1981 – REVISED JANUARY 2016 SN74LS29x Programmable Frequency Dividers and Digital Timers
1 Features 3 Description The SN74LS29x devices are programmable
frequency dividers and digital timers contain 31 flipflops plus 30 gates (in SN74LS292) or 15 flip-flops
plus 29 gates (in SN74LS294) on a single chip. The
count modulo is under digital control of the inputs
provided. 1 Count Divider Chain
Digitally Programmable from 22 to 2n
(n = 31 for SN74LS292 , n = 15 for SN74LS294)
Useable Frequency Range from DC to 30 MHz
Easily Expandable Both types feature an active-low CLR clear input to
initialize the state of all flip-flops. To facilitate the
incoming inspection, test points are provided (TP1,
TP2, and TP3 on the SN74LS292, and TP on the
SN74LS294). These test points are not intended to
drive system loads. Both types feature two clock
inputs; either one may be used for clock gating (see
Table 1). 2 Applications Frequency Division …
