FEATURES
74LVT534
DESCRIPTION
• 3-State outputs for bus interfacing
• Common output enable
• TTL input and output switching levels
• Input and output interface capability to systems at 5 V supply
• Bus-hold data inputs eliminate the need for external pull-up
The LVT534 is a high-performance BiCMOS product designed for
VCC operation at 3.3 V.
This device is an 8-bit, edge triggered register coupled to eight
3-State output buffers. The two sections of the device are controlled
independently by the clock (CP) and Output Enable (OE) control
gates. 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.
resistors to hold unused inputs
• Live insertion/extraction permitted
• No bus current loading when output is tied to 5 V bus
• Power-up 3-State
• Power-up reset
• Latch-up protection exceeds 500mA per JEDEC Std 17
• ESD protection exceeds 2000 V per MIL STD 883 Method 3015
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
independent 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, which
means they will neither drive nor load the bus.

NOTES:
1. Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the
device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to
absolute-maximum-rated conditions for extended periods may affect device reliability.
2. The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction
temperatures which are detrimental to reliability. The maximum junction temperature of this integrated circuit should not exceed 150 °C.
3. The input and output negative voltage ratings may be exceeded if the input and output clamp current ratings are observed.

NOTES:
1. All typical values are at VCC = 3.3 V and Tamb = 25 °C.
2. This is the increase in supply current for each input at the specified voltage level other than VCC or GND.
3. This parameter is valid for any VCC between 0 V and 1.2 V with a transition time of up to 10 msec. From VCC = 1.2 V to VCC = 3.3 V ± 0.3 V
a transition time of 100 µsec is permitted. This parameter is valid for Tamb = 25 °C only.
4. Unused pins at VCC or GND.
5. For valid test results, data must not be loaded into the flip-flops (or latches) after applying power.
6. ICCZ is measured with outputs pulled to VCC or down to GND.
7. This is the bus hold overdrive current required to force the input to the opposite logic state.
