Product data sheet
1. General description
The 74LVT16245B; 74LVTH16245B is a high-performance BiCMOS product designed for
VCC operation at 3.3 V.
This device is a 16-bit transceiver featuring non-inverting 3-state bus compatible outputs
in both send and receive directions. The control function implementation minimizes
external timing requirements. The device features an output enable input (nOE) for easy
cascading and a direction input (nDIR) for direction control.
2. Features and benefits
16-bit bidirectional bus interface
3-state buffers
Output capability: +64 mA and 32 mA
TTL input and output switching levels
Input and output interface capability to systems at 5 V supply
Bus hold data inputs eliminate need for external pull-up resistors to hold unused inputs
Live insertion and extraction permitted
Power-up 3-state
No bus current loading when output is tied to 5 V bus
Latch-up protection:
JESD78B Class II exceeds 500 mA
ESD protection:
HBM JESD22-A114F exceeds 2000 V
MM JESD22-A115-A exceeds 200 V
