描述 Description

16-bit edge-triggered D-type flip-flop - The 74LVCH162374A is a 16-bit edge triggered flip-flop featuring separate D-type inputs for each flip-flop and 3-state outputs for bus-oriented applications. The device consists of two sections of 8 edge-triggered flip-flops. A clock (CP) input and an output enable (OE) are provided for each octal. Inputs can be driven from either 3.3 V or 5 V devices. When disabled, up to 5.5 V can be applied to the outputs. These features allow the use of these devices in mixed 3.3 V and 5 V applications. The flip-flops store the state of their individual D-inputs that meet the set-up and hold time requirements on the LOW to HIGH CP transition. When OE is LOW, the contents of the flip-flops are available at the outputs. When OE is HIGH, the outputs go to the high-impedance OFF-state. Operation of the OE input does not affect the state of the flip-flops. Bus hold on data inputs eliminates the need for external pull-up resistors to hold unused inputs. To reduce line noise, 30 Ω series termination resistors are included in both high and low output stages.
