INTEGRATED CIRCUITS 74ALVT16260 12-bit to 24-bit multiplexed D-type latches (3-State) Product specification IC23 Data Handbook 1998 Jan 30 Philips Semiconductors Product specification 2.5V/3.3V 12-bit to 24-bit multiplexed D-type latches (3-State) FEATURES 74ALVT16260 DESCRIPTION • ESD protection exceeds 2000V per Mil-Std-883C, Method 3015; The 74ALVT16260 is a 12-bit to 24-bit multiplexed D-type latch used in applications where two separate data paths must be multiplexed onto, or demultiplexed from, a single data path. Typical applications include multiplexing and/or demultiplexing of address and data information in microprocessor or bus-interface applications. This device is alto useful in memory-interleaving applications. exceeds 200V using machine model • Latch-up protection exceeds 500mA per JEDEC Standard JESD-17. • Distributed VCC and GND pin configuration minimizes high-speed Three 12-bit I/O ports (A1–A12, 1B1–1B12, and 2B1–2B12) are available for address and/or data transfer. The output enable (OE1B, OE2B, and OEA) inputs control the bus transceiver functions. The OE1B and OE2B control signals also allow bank control in the A to B direction. switching noise. • Output capability (–32mA IOH, 64mA IOL). • Bus hold inputs eliminate the need for external pull-up resistors. • 5V I/O compatible • Live insertion/extraction permitted • Power-up 3-State • Power-up Reset Address and/or data information can be stored using the internal storage latches. The latch enable (LE1B, LE2B, LEA1B, and LEA2B) inputs are used to control data storage. When the latch enable input is high, the latch is transparent. When the latch enable input goes low, the data present at the inputs is latched and remains latched until the latch enable input is returned high. To ensure the high-impedance state during power-up or power-down, OE should be tied to VCC through a pull-up resistor; the minimum value of the resistor is determined by the current sinking capability of the driver. The 74ALVT16260 is available in a 56-pin Shrink Small Outline Package (SSOP) and 56-pin Thin Shrink Small Outline Package (TSSOP).
