74HC590

8-bit binary counter with output register; 3-state

Rev. 02 — 28 April 2009

Product data sheet

1. General description

The 74HC590 is a high-speed Si-gate CMOS device and is pin compatible with Low

power Schottky TTL (LSTTL). It is speciﬁed in compliance with JEDEC standard no. 7A.

The 74HC590 is an 8-bit binary counter with a storage register and 3-state outputs. The

storage register has parallel (Q0 to Q7) outputs. The binary counter features a master

reset counter (MRC) and count enable (CE) inputs. The counter and storage register have

separate positive edge triggered clock (CPC and CPR) inputs. If both clocks are

connected together, the counter state always is one count ahead of the register. Internal

circuitry prevents clocking from the clock enable. A ripple carry output (RCO) is provided

for cascading. Cascading is accomplished by connecting RCO of the ﬁrst stage to CE of

the second stage. Cascading for larger count chains can be accomplished by connecting

RCO of each stage to the counter clock (CPC) input of the following stage. If both clocks

are connected together, the counter state always is one count ahead of the register.
