74HC161	文件：83.61 Kbytes Page：12 Pages	Presettable synchronous 4-bit binary counter; asynchronous reset GENERAL DESCRIPTION The 74HC/HCT161 are high-speed Si-gate CMOS devices and are pin compatible with low power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard no. 7A. FEATURES • Synchronous counting and loading • Two count enable inputs for n-bit cascading • Positive 文件：83.61 Kbytes 页数：12 Pages	PHI PHI	PHI
74HC161	文件：279.75 Kbytes Page：17 Pages	Presettable synchronous 4-bit binary counter; asynchronous reset 1. General description The 74HC161 is a synchronous presettable binary counter with an internal look-head carry. Synchronous operation is provided by having all flip-flops clocked simultaneously on the positivegoing edge of the clock (CP). The outputs (Q0 to Q3) of the counters may be preset HI 文件：279.75 Kbytes 页数：17 Pages	NEXPERIA 安世	NEXPERIA
