Is Now Part of To learn more about ON Semiconductor, please visit our website at www.onsemi.com Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor product management systems do not have the ability to manage part nomenclature that utilizes an underscore (_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please email any questions regarding the system integration to Fairchild_questions@onsemi.com.

T E When the MM74HCT373 LATCH ENABLE input is HIGH, the Q outputs will follow the D inputs. When the LATCH O ENABLE goes LOW, data at the D inputs will be retained at c t the outputs until LATCH ENABLE returns HIGH again. a When a high logic level is applied to the OUTPUT CON- l D TROL input, all outputs go to a high impedance state, - T regardless of what signals are present at the other inputs y and the state of the storage elements. p e The MM74HCT374 are positive edge triggered flip-flops. Data at the D inputs, meeting the setup and hold time L a requirements, are transferred to the Q outputs on positive t c going transitions of the CLOCK (CK) input. When a high h logic level is applied to the OUTPUT CONTROL (OC) (cid:127) input, all outputs go to a high impedance state, regardless 3 - of what signals are present at the other inputs and the state S of the storage elements. T A MM74HCT devices are intended to interface between TTL T and NMOS components and standard CMOS devices.
