2 / 12 page Philips Semiconductors Product specification 74ALVT16245 2.5V/3.3V 16-bit transceiver (3-State) 2 1998 Feb 13 853-1817 18959 FEATURES • 16-bit bidirectional bus interface • 5V I/O Compatible • 3-State buffers • Output capability: +64mA/–32mA • TTL input and output switching levels • Bus-hold data inputs eliminate the need for external pull-up resistors to hold unused inputs • Live insertion/extraction permitted • 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 400V per Machine Model DESCRIPTION The 74ALVT16245 is a high-performance BiCMOS product designed for VCC operation at 2.5V or 3.3V with I/O compatibility up to 5V. 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 (OE) input for easy cascading and a Direction (DIR) input for direction control.
