74LVT162245B
3.3 V 16-bit transceiver with 30 Ω termination resistors;
3-state
Rev. 3 — 1 October 2018
Product data sheet
1. General description
The 74LVT162245B 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.
The 74LVT162245B is designed with 30 Ω series resistance in both the HIGH-state and LOW-state
of the output. This design reduces line noise in applications such as memory address drivers, clock
drivers and bus transceivers and transmitters.
2. Features and benefits
16-bit bidirectional bus interface
3-state buffers
Output capability: +12 mA/–12 mA
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 resistors to hold unused inputs
Live insertion/extraction permitted
Outputs include series resistance of 30 Ω making external termination resistors unnecessary
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
