Rev. 01 — 13 July 2009
Product data sheet
1. General description
The 74LVTN16244B is a high-performance BiCMOS product designed for VCC operation
at 3.3 V.
This device is a 16-bit buffer and line driver featuring non-inverting 3-state bus outputs.
The device can be used as four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer.
2. Features
I 16-bit bus interface
I 3-state buffers
I Output capability: +64 mA and −32 mA
I TTL input and output switching levels
I Input and output interface capability to systems at 5 V supply
I Power-up 3-state
I Live insertion and extraction permitted
I No bus current loading when output is tied to 5 V bus
I Latch-up protection
N JESD78 Class II exceeds 500 mA
I ESD protection:
N HBM JESD22-A114E exceeds 2000 V
N MM JESD22-A115-A exceeds 200 V
