2 / 10 page Philips Semiconductors Product specification 74LVT162240A 3.3V 16-bit inverting buffer/driver with 30 Ω termination resistors (3-State) 2 1998 Feb 19 853-1777 18990 FEATURES • 16-bit bus interface • 3-State buffers • Output capability: +12mA/-12mA • TTL input and output switching levels • Input and output interface capability to systems at 5V 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 30Ω making external termination resistors unnecessary • Power-up 3-State • No bus current loading when output is tied to 5V bus • Latch-up protection exceeds 500mA per JEDEC Std 17 • ESD protection exceeds 2000V per MIL STD 883 Method 3015 and 200V per Machine Model • Same part as 74LVT16240A-1 DESCRIPTION The 74LVT162240A is a high-performance BiCMOS product designed for VCC operation at 3.3V. This device is an inverting 16-bit buffer that is ideal for driving bus lines. The device features four Output Enables (1OE, 2OE, 3OE, 4OE), each controlling four of the 3-State outputs. The 74LVT162240A is designed with 30 Ω series resistance in both the pull-up and pull-down output structures. This design reduces line noise in applications such as memory address drivers, clock drivers, and bus receivers/transmitters. The 74LVT162240A is the same as the 74LVT16240A-1. The part number has been changed to reflect industry standards.
