The SN74LS569N is a 20-pin dual 4-bit binary counter with decoder and latch manufactured by Texas Instruments. It is a low-power Schottky TTL (LSTTL) logic device. Description: The SN74LS569N is a dual 4-bit binary counter with decoder and latch. It has two 4-bit binary counters, each with a separate clock input (CP1 and CP2) and a common reset input (MR). The counters are enabled by the decoder and latch, which are activated by a low-level signal at the enable input (E). The decoder and latch provide a low-level output at the output enable (OE) when enabled.
