2 / 10 page Philips Semiconductors Product specification 74LVC377 Octal D-type flip-flop with data enable; positive-edge trigger 2 1998 Jul 29 FEATURES • Wide supply voltage range of 1.2V to 3.6V • Conforms to JEDEC standard 8-1A • Inputs accept voltages up to 5.5V • CMOS low power consumption • Direct interface with TTL levels • Output drive capability 50Ω transmission lines @ 85°C DESCRIPTION The 74LVC377 is a low-voltage Si-gate CMOS device, superior to most advanced CMOS compatible TTL families. The 74LVC377 has eight edge-triggered , D-type flip-flops with individual D inputs and Q outputs. A common clock (CP) input loads all flip-flops simultaneously when the data enable E is LOW. The state of each D input, one set-up time before the LOW-to-HIGH clock transition, is transferred to the corresponding output (Qn) of the flip-flop. The E input must be stable only one set-up time prior to the LOW-to-HIGH transition for predictable operation.
