Rev. 08 — 22 March 2010
Product data sheet
1. General description
The 74LVT16244B; 74LVTH16244B is a high-performance BiCMOS product designed for
V
CC
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 and benefits
16-bit 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
Power-up 3-state
Live insertion and extraction permitted
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
