It is ideal for low power, battery operated and low noise 3.3V applications. SOP TSSOP Table 1: Order Codes PACKAGE T&R SOP TSSOP 74LVX74MTR 74LVX74TTR A signal on the D INPUT is transferred to the Q OUTPUT during the positive going transition of the clock pulse. CLR and PR are independent of the clock and accomplished by a low setting on the appropriate input. Power down protection is provided on all inputs and 0 to 7V can be accepted on inputs with no regard to the supply voltage. This device can be used to interface 5V to 3V system. It combines high speed performance with the true CMOS low power consumption. All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.
