1 / 8 page  Philips Semiconductors Products Product specification MB2377 Dual octal D-type flip-flop with enable 1 August 23, 1993 853-1666 10588 FEATURES • Ideal for addressable register applications • Two 8-bit positive edge-triggered registers • Two Enable inputs for address and data synchronization applications • Power-up reset • Output capability: +64mA/–32mA • Latch-up protection exceeds 500mA per Jedec JC40.2 Std 17 • ESD protection exceeds 2000 V per MIL STD 883 Method 3015 and 200 V per Machine Model DESCRIPTION The MB2377 high-performance BiCMOS device combines low static and dynamic power dissipation with high speed and high output drive. The MB2377 has two 8-bit, edge triggered registers, with individual D inputs and Q outputs. The common buffered clock (1CP or 2CP) input will load a set of eight flip-flops simultaneously when the corresponding Enable (1E or 2E) input is Low. The registers are fully edge triggered. The state of each D input, one set-up time before the Low-to-High clock transition, is transferred to the corresponding flip-flop’s Q output. The nE inputs must be stable one setup time prior to the Low-to-High clock transition for predictable operation.
