P1-P3P4-P6P7-P9P10-P12P13-P15
74LVT2245; 74LVTH2245
3.3 V octal transceiver with 30 Ω termination resistors; 3-state
Rev. 5 — 10 April 2017 Product data sheet
1 General description
The 74LVT2245; 74LVTH2245 is a high-performance BiCMOS product designed for V
CC
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 control function implementation minimizes
external timing requirements. The device features an output enable input (OE) for easy
cascading and a direction input (DIR) for direction control.
The 74LVT2245; 74LVTH2245 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
• 30 Ω output termination resistors
• Octal bidirectional bus interface
• 3-state buffers
• Output capability: +12 mA and -12 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:
– JESD78: exceeds 500 mA
• ESD protection:
– MIL STD 883 method 3015: exceeds 2000 V
– MM JESD22-A115-A exceeds 200 V (C = 200 pF, R = 0 Ω)
