1. general description the 74abt374a high-performance bicmos dev ice combines low static and dynamic power dissipation with high sp eed and high output drive. the 74abt374a is an 8-bit, edge triggered r egister coupled to eight 3-state output buffers. the two sections of the device ar e controlled independently by the clock input (cp) and output enable input (oe ) control gates. the register is 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 3-state output buffers are designed to drive heavily loaded 3-state buses, mos memories, or mos microprocessors. the active low output enable (oe ) controls all eight 3-state buffers independ ent of the clock operation. when oe is low, the stored data appears at the outputs. when oe is high, the outputs are in the high-impedance ?off? state, whic h means they will neither drive nor load the bus. 2. features and benefits ? 8-bit positive edge triggered register ? 3-state output buffers ? power-on 3-state ? power-on reset ? output capability: +64 ma/ ? 32 ma ? latch-up protection exceeds 500 ma per jesd78b class ii level a ? esd protection: ? hbm jesd22-a114f exceeds 2000 v ? mm jesd22-a115-a exceeds 200 v ? live insertion/extraction permitted 74abt374a octal d-type flip-flop; posit ive-edge trigger; 3-state rev. 2 ? 18 december 2012 product data sheet
