74LVC823A
9-bit D-type flip-flop with 5 V tolerant inputs/outputs; positive
edge-trigger; 3-state
Rev. 4 — 8 April 2013
Product data sheet
1. General description
The 74LVC823A is a 9-bit D-type flip-flop with common clock (pin CP), clock enable
(pin CE), master reset (pin MR) and 3-state outputs (pins Qn) for bus-oriented
applications. The 9 flip-flops stores the state of their individual D-inputs that meet the
set-up and hold times requirements on the LOW to HIGH CP transition, provided pin CE is
LOW. When pin CE is HIGH, the flip-flops hold their data. A LOW on pin MR resets all
flip-flops. When pin OE is LOW, the contents of the 9 flip-flops are available at the outputs.
When pin 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.
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 as translators in
mixed 3.3 V and 5 V applications.
2. Features and benefits
5 V tolerant inputs/outputs for interfacing with 5 V logic
Wide supply voltage range from 1.2 V to 3.6 V
CMOS low power consumption
Direct interface with TTL levels
Flow-through pinout architecture
9-bit positive edge-triggered register
Independent register and 3-state buffer operation
Complies with JEDEC standard:
JESD8-7A (1.65 V to 1.95 V)
JESD8-5A (2.3 V to 2.7 V)
JESD8-C/JESD36 (2.7 V to 3.6 V)
ESD protection:
HBM JESD22-A114F exceeds 2000 V
MM JESD22-A115-B exceeds 200 V
CDM JESD22-C101E exceeds 1000 V

(1) This is not a supply pin. The substrate is attached to this
pad using conductive die attach material. There is no
electrical or mechanical requirement to solder this pad.
However, if it is soldered, the solder land should remain
floating or be connected to GND.
