74LCX273

Low-Voltage Octal D Flip-Flop

with 5V Tolerant Inputs and Outputs

General Description

Features

5V tolerant inputs and outputs

The LCX273 has eight edge-triggered D-type flip-flops with

individual D inputs and Q outputs. The common buffered

Clock (CP) and Master Reset (MR) input load and reset

(clear) all flip-flops simultaneously.

10 mA I

max

CCQ

Power-down high impedance inputs and outputs

Supports live insertion/withdrawal

The register is fully edge-triggered. The state of each D in-

put, one setup time before the LOW-to-HIGH clock tran-

sition, is transferred to the corresponding flip-flop’s Q out-

put.

2.0V–3.6V V supply operation

24 mA output drive

Implements patented Quiet Series^TMnoise/EMI

reduction circuitry

All outputs will be forced LOW independently of Clock or

Data inputs by a LOW voltage level on the MR input. The

device is useful for applications where the true output only is

required and the Clock and Master Reset are common to all

storage elements.

Functionally compatible with the 74 series 273

Latch-up performance exceeds 500 mA

ESD performance:

200V

Human Body Model

2000V

Machine Model

The device is designed for low voltage (3.3V) V

applica-

tions with capability of interfacing to a 5V signal environ-

ment. The LCX273 is fabricated with an advanced CMOS

technology to achieve high speed operation while maintain-

ing CMOS low power dissipation.
