1. General description
The 74LVT245 is a high-performance BiCMOS product designed for VCC operation at
3.3 V.
This device is an octal transceiver featuring non-inverting 3-state bus compatible outputs
in both send and receive directions. The contr ol function implementation minimizes
external timing requirements. It features an output enable (OE) input for easy cascading
and a direction (DIR) input for direction control.
2. Features and benefits
3-state buffers
Octal bidirectional bus interface
Input and output interface capability to systems at 5 V supply
TTL input and output switching levels
Output capability: +64 mA/32 mA
Latch-up protection exceeds 500 mA per JESD78 class II level A
ESD protection:
HBM JESD22-A114E exceeds 2000 V
MM JESD22-A115 -A ex ce eds 20 0 V
Bus-hold data inputs eliminate the need for external pull-up resistors for unused inputs
Live insertion/ extraction permitted
Power-up 3-state
No bus current loading when output is tied to 5 V bus

[1] H = HIGH voltage level;
L = LOW voltage level;
X = don’t care;
Z = high impedance OFF-state.
7. Limiting values
[1] S tresses 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 en vironment 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.
[4] For SO20 packages: above 70 C derate linearly with 8 mW/K.
For SSOP20 and TSSOP20 packages: above 60 C derate linearly with 5.5 mW/K.
For DHVQFN20 packages: above 60 C derate linearly with 4.5 mW/K.
