2 / 14 page Philips Semiconductors Product specification 74LVT652 3.3V Octal transceiver/register, non-inverting (3-State) 2 1998 Feb 19 853-1748 18987 FEATURES • Independent registers for A and B buses • Multiplexed real-time and stored data • 3-State outputs • Output capability: +64mA/–32mA • 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 • No bus current loading when output is tied to 5V bus • Power-up 3-State • Power-up reset • Latch–up protection exceeds 500mA per JEDEC Std 17 • ESD protection exceeds 2000V per MIL STD 883 Method 3015 and 200V per Machine Model DESCRIPTION The LVT652 is a high-performance BiCMOS product designed for VCC operation at 3.3V. This device combines low static and dynamic power dissipation with high speed and high output drive. The 74LVT652 transceiver/register consists of bus transceiver circuits with 3-State outputs, D–type flip-flops, and control circuitry arranged for multiplexed transmission of data directly from the input bus or the internal registers. Data on the A or B bus will be clocked into the registers as the appropriate clock pin goes High. Output Enable (OEAB, OEBA) and Select (SAB, SBA) pins are provided for bus management.
